Planning an upgrade


Before you start an upgrade, review this planning guide to select the appropriate upgrade method and to understand the upgrade process.

In this topic


Choosing an upgrade path

Your current version of the BMC Remedy ITSM Suite platform components and applications determines the upgrade path that you choose. Review the planning decisions and related information in the table to plan your upgrade path.

Planning decision

 Details
From which versions can I upgrade?

You can upgrade directly to BMC Remedy ITSM Suite from BMC Remedy ITSM 7.6.04 or a later version.

Remedy Platform Upgrade:


Remedy Applications Upgrade:


Let us consider the following scenarios when you are upgrading to the latest version of Remedy:

Upgrading to the latest Remedy version from 18.08

You can directly upgrade your Remedy 18.08 platform to the latest version by using the installer. However, to upgrade Remedy applications from 18.08 to the latest version, you need to apply the latest deployment package.

Upgrading from Remedy version 9.x

You can directly upgrade your Remedy 9.x platform to the latest version by using the installer. However, to upgrade Remedy applications from 8.x or 9.x to the latest version, you need to use the 18.05 installer, and then you can upgrade the applications from version 18.05 to the latest version by applying the latest deployment package.

How do I upgrade from a version earlier than 7.6.04? 

If you are upgrading from a version earlier than BMC Remedy ITSM 7.6.04, you must first upgrade to BMC Remedy ITSM 8.1.02. For instructions, see Upgrading in the BMC Remedy ITSM Suite 8.1 Deployment documentation.

Best Practice

BMC recommends that you sign up for the AMIGO program to discuss options for upgrading from a version earlier than 7.6.04. For more information, see Upgrade planning assistance.

What is the difference between upgrading from a version earlier than 7.6.04 and from version 7.6.04 or later?

In BMC Remedy Action Request System 7.6.04, the overlays feature was introduced to preserve application customizations during the upgrade process. During the upgrade, the upgrade installers ignore application overlays and change only the objects that were originally installed with the application or server. After the upgrade, the application or server continues to use the overlays instead of the origin objects for run-time operations so that your customizations are preserved. 

If you are upgrading from a release that was customized without overlays, you will need to create overlays for those existing application customizations before you upgrade. This process is part of the 8.1.02 upgrade. For details about the process, see Creating overlays in the BMC Remedy ITSM Suite 8.1 Deployment documentation.

How do I upgrade from version 7.6.04 or later?

The Best Practice Customization mode of BMC Remedy Developer Studio ensures that all application object customizations are saved as overlays when you upgrade. If you have already created overlays, you can directly upgrade each component to the latest version.

In BMC Remedy AR system version 8.1, granular overlays were introduced to minimize the amount of reconciliation you need to perform following an upgrade or patch. Granular overlays allow you to modify only some aspects of an object and inherit other aspects from the origin object. When you upgrade to 9.1, you might need to adjust your overlays prior to installing BMC Remedy ITSM and reconciling. For details, see Adjusting customizations when upgrading.

What is the BMC Remedy ITSM CI Attribute change, and why do I need to make these changes when I upgrade?

Earlier versions of BMC Remedy ITSM extended the BMC Atrium Configuration Management Database (CMDB) data model by adding a number of ITSM-specific attributes to CI classes. Starting in BMC Remedy ITSM version 8.0, these attributes are now stored in the ITSM Foundation instead of the BMC Atrium CMDB.

During the upgrade, the installer will copy the ITSM attributes from the CMDB to the ITSM Foundation and will put a workflow in place to keep the attributes up to date in both locations. For more information, see Performing the BMC Remedy ITSM upgrade.


Determining the upgrade scope

Depending on your business needs, you can incrementally upgrade your Remedy system. Review the planning decisions and related information in the table to plan the upgrade scope and decide whether to deploy new components. 

Planning decision

Details
Which versions of the platform and applications are supported together?

You must review the compatible BMC product versions in the compatibility matrix to understand which supported versions of the BMC Remedy ITSM applications are supported with the platform components.

The Remedy platform offers backward compatibility with older versions of Remedy applications. This allows you to upgrade the platform without having to upgrade your applications. Customers with BMC Remedy AR platform as their core stack and custom applications running on top of the platform can just upgrade the platform. 

Important

You must ensure that all the application components are at the same version. For example, if you upgrade BMC Remedy ITSM to 18.08 with Process Designer version 9.1, it is necessary to upgrade BMC Service Request Management to version 18.08. You should also keep BMC Remedy Mid Tier, AR Server and Smart Reporting on the same version.

For BMC Digital Workplace, see Compatibility matrix in the BMC Digital Workplace documentation.

Can I upgrade just the platform components?

Yes.

You can upgrade the platform components (BMC Remedy AR System and BMC Atrium Core) separately from any applications on the system. You must upgrade the AR System server and the Atrium Configuration Management Database (CMDB) together, and they must be at the same version. You can perform an in-place upgrade the platform components with zero downtime if they are deployed in a server group environment.

You must upgrade BMC Remedy Mid Tier to 18.08 or 18.05 at the same time or before upgrading the AR System server and the Atrium Core CMDB. AR System Server 18.05 introduces new dynamic data menus that do not work if a lower version of Mid Tier is used against AR System Server 18.05 or 18.08

Can I upgrade just the applications?

No.

You must upgrade the platform before you can upgrade the applications. The applications must be at the same version as the platform (or the platform can be at a later version than the applications). 

However, you can upgrade the applications during a different upgrade period. For example, you might upgrade the platform one month or one week prior to the applications. 

What BMC integrations do I need to upgrade?

Review the compatibility matrix to check whether the version of your BMC integrations are supported with this version of the Remedy platform. Not all BMC products are listed in the compatibility matrix. In this case, check the system requirements or documentation for the integration, such as the following products:

  • BMC TrueSight Infrastructure Management
  • BMC Service Resolution
When should I upgrade BMC Remedy with Smart IT or BMC Digital Workplace?

The upgrade process is separate for BMC Remedy with Smart IT or BMC Digital Workplace.

If you are using BMC Digital Workplace and/or BMC Remedy with Smart IT, it is recommended that you upgrade the BMC Remedy ITSM Suite only after upgrading BMC Digital Workplace and upgrade Smart IT only after BMC Remedy ITSM is upgraded.

Note that if ITSM is upgraded to version 18.05, Smart IT also must be upgraded to 18.05, because Smart IT 2.0 and earlier will not work with ITSM 18.05.

The upgrade sequence is as follows:

  1. Upgrade to BMC Digital Workplace
  2. Upgrade to Remedy ITSM Suite
  3. Upgrade to Remedy with Smart IT

For more information, see Upgrading BMC Digital Workplace in the Digital Workplace documentation and Upgrading Smart IT in the Smart IT documentation.

Do I need to migrate to BMC Remedy Single Sign-On from BMC Atrium Single Sign-On?

BMC Atrium Single Sign-On is not supported for BMC Remedy Action Request System 9.1.00 and later versions. BMC supports only BMC Remedy Single Sign-On with BMC Remedy Action Request System 9.1.00 and later versions.

If you have already migrated to BMC Remedy Single Sign-On, you can upgrade to the current version, which is separate from the BMC Remedy ITSM Suite upgrade. For information about how to install or upgrade, see the documentation for BMC Remedy Single Sign-On .


Choosing the upgrade method

There are two methods for upgrading the BMC Remedy ITSM Suite: staged upgrade or in-place upgrade. Depending on the complexity of your environment and your outage window, choose a method that suites your requirements. Review the planning decisions and related information in the table to select an upgrade method.

Planning decision

Details

What is an in-place upgrade?


An in-place upgrade encompasses the following:

  • You leverage your existing hardware and Remedy environments (development, QA, and production).

  • While upgrading your development system, you test the upgrade of the platform components and applications and reconcile application customizations (overlays).

  • While upgrading your QA system, you test the upgrade of the platform components and applications with production data and fully test the upgraded environment.

    Best Practice

    BMC highly recommends that you conduct full validation and performance testing in the QA environment to minimize the amount of time required for testing during the production upgrade.
  • In your current production environment, you perform the final upgrade and import your reconciled application customizations. 

What is a staged upgrade?


A staged upgrade encompasses the following:

  • You set up staging servers that are clones of your current Remedy environments. If you need to upgrade your hardware or database, you set up new systems.
  • While upgrading your development system, you test the upgrade of the platform components and applications and reconcile application customizations (overlays).

  • While upgrading your QA system, you test the upgrade of the platform components and applications with production data and fully test the upgraded environment.

    Best Practice

    BMC highly recommends that you conduct full validation and performance testing in the QA environment to minimize the amount of time required for testing during the production upgrade. Reducing test time during the production phase will also reduce the amount of delta data that you need to migrate.
  • In the production staging environment, you perform the final upgrade, import your reconciled application customizations, and migrate the delta data by using the Delta Data Migration tool. (Delta data refers to any data changes that occur on the production server during the upgrade of the staging server.)
  • Your current production environment is preserved and remains available to users while you perform the upgrade process.

Do I need to schedule downtime for the upgrade?
  • You can perform an in-place upgrade of  the Remedy platform (BMC Remedy AR System and BMC Atrium Core) with no downtime. Production work can continue while the upgrade processes in the background. However, there is always a possibility of some reduction in throughput. An additional load is generated in parallel to the live system; therefore, BMC recommends that you perform the upgrade during off-peak hours. To prepare for the zero-downtime upgrade of the platform components, see Preparing for zero-downtime upgrade of the platform.

  • You must schedule downtime for the application upgrade.

  • When you perform zero-downtime upgrade in a non-server group environment, the installer automatically adds all the upgraded servers to the server group. If there are servers which are not upgraded to 9.1.04 but are using the 9.1.04 database, those servers are not added to the server group.

Planning the upgrade environment

When you upgrade to a new version, you might need to provision for newer hardware to support your deployment and update third-party software. Review the planning decisions and related information to plan the upgraded environment.

Planning decisionDetails
What are the hardware requirements?

Important

You must review the recommended Hardware requirements for your deployment to determine whether you need to upgrade the hardware, both primary servers and secondary servers in a server group.

Also review the following sections in the documentation:

What is the recommended sizing guideline?

BMC publishes guidelines for hardware sizing based on a series of enterprise-scale tests to demonstrate the scalability and performance of the platform and the applications.

Best Practice

BMC recommends that you adequately estimate and size your environment for continued scalability and performance. The medium-size deployment model specified in the hardware requirements is suited for the majority of our customers. If you need additional capacity, BMC recommends that you add an additional medium-size server to a server group.

The product installers automatically run the preupgrade checks and configuration checks based on BMC's medium size best-practice sizing recommendations.

Will I need additional hardware?

If you decide to perform a staged upgrade, you will need additional hardware for the development, QA, and production staging servers. To understand staging server implementation, see Setting up a staged upgrade server.

What are the software requirements?

Important

You must review the compatibility matrix to ensure the current systems contain the supported third-party software, supported databases, and supported operating systems.

Also review the following sections in the documentation:

For network port requirements, see

Which databases are supported?

For database support, see the database requirements in the compatibility matrix and in the Hardware requirements. Also review Unicode support.


Planning pre-upgrade activities

Details
What preparations do I need to make before I begin?

The Preparing section describes general preparation tasks, such as downloading the installation files.

For each component, there are also pre-upgrade steps that you need to follow.

Where should I document my installation details?

Before you start installing or upgrading products, you might want to first gather your responses to the installer prompts for each product in the installation spreadsheet. The installation spreadsheet provides guidance on what needs to be entered for an upgrade and helps you collect these parameter values to reduce errors during the upgrade process.

For more information, see Completing the installation spreadsheet.

What should I test during the upgrade?

See Performing upgrade testing.

Best Practice

To minimize testing in the final phase of upgrade, BMC recommends that perform extensive testing in your QA environment. To do so requires the QA environment to closely match the capabilities and the load on the current production environment.



Are there any tools that I will need to perform the upgrade?

Yes. 

For details, see Installing upgrade utilities.

Where can I find information about issues I need to be aware of?

For the latest patch information or bulletins, see Release notes and notices. For details about known issues in this release, see:
