Step Action Additional information

Pre-upgrade procedures

1. Take a snapshot of the production server by using Developer Studio Snapshot utility. The Developer Studio Snapshot is not an offcial utility. You can download it from BMC Communities. See https://communities.bmc.com/docs/DOC-17012.
2.

Optionally,

review the preupgrade checks and configuration checks
 

You can use the Configuration Check utility to perform the following checks:

  • Preupgrade checks before you upgrade any or all of the components in the BMC Remedy IT Service Management (ITSM) Suite environment
  • General configuration checks on your system, before you install any component in the BMC Remedy ITSM Suite environment.

BMC recommends that you perform this activity as part of the Preparing stage.

3. Recommendations for upgrading BMC Remedy AR System Review the recommendations before you proceed.
4. Ensure that you have enough transactional log space for an upgrade.

During the upgrade, the production dataset record data is copied from the BMC Atrium CMDB BMC.CORE:BMC_BaseElement form to a new AST:Attributes form. Ensure that you have enough transactional log space to accommodate the new form.

5. If you are upgrading from a version earlier than 7.6.03, prepare Full Text Search (FTS). Perform these activities only if you are upgrading from a version earlier than 7.6.03.
6. Prepare approval server for upgrade

These activities preserve customizations and ensure that definition files are updated successfully.

Perform the upgrade
1. Perform the BMC Remedy AR System Server upgrade

This action upgrades the BMC Remedy AR System server, Approval Server, Assignment Engine, Email Engine, and Flashboards. It also installs the following plug-ins: AREA LDAP, ARDBC, Web Services, SNMP, and FTS.

Postupgrade procedures
1. Validate the upgrade
  • Review the log files
  • Create a zip file of the logs using the maintenance tool
  • Perform a health check
2. Adjust customizations BMC recommends that you adjust your customizations and assign the appropriate overlay type to the objects' granular sections before proceeding with the BMC Remedy AR System application upgrade.
3. If you are upgrading from BMC Remedy AR System 7.6.04 with view overlays present, perform the postupgrade steps Perform the postupgrade steps before you start using the view overlay with the upgraded AR System server.
4. Compare objects after you upgrade with overlays already present

To check for differences between two sets of objects, use BMC Remedy Migrator. To examine the different objects to determine whether you will need to merge changes, use BMC Remedy Developer Studio.

For a list of all of the overlay objects that were modified in the latest release, obtain the Snapshot utility (a Developer Studio plug-in). This unsupported utility is available on the BMC Developer Network.

5. Disable ServletExec after the upgrade (Windows or UNIX) If you are upgrading and you do not want to use the ServletExec application server, perform the steps described in this section to disable it.
6. Perform the Approval Server postupgrade steps If you upgraded BMC Remedy Approval Server after backing up your data and customizations, perform the steps described in this section.
7. Perform the Developer Studio postupgrade procedures Ensure that the correct plug-ins are in the Developer Studio folder.
8. Enable LDAP plug-ins for SSL connections after the upgrade To enable LDAP plug-ins for SSL connections in configured networks after an upgrade, you must add an LDAP certificate to the certificate database for SSL communication.
9. Perform the IPv6 postupgrade steps

You must update Java paths and configuration after upgrading and changing from IPv4 to IPv6.

Upgrade BMC Remedy Encryption Security 

Step Action Additional Information
1. Perform the BMC Remedy Encryption Security upgrade

Upgrade BMC Atrium CMDB 

Step Action Additional Information
Pre-upgrade procedures
1.

Optionally,

review the preupgrade checks and configuration checks

You can use the Configuration Check utility to perform the following checks:

  • Preupgrade checks before you upgrade any or all of the components in the BMC Remedy IT Service Management (ITSM) Suite environment.
  • General configuration checks on your system, before you install any component in the BMC Remedy ITSM Suite environment.

BMC recommends that you perform this activity as part of the Preparing stage.

2. Prepare your operating system and your server before you upgrade BMC Atrium Core All BMC Atrium Core versions have steps in common. You must comment out the entries in the armonitor and ar configuration files. Also, perform a complete health check of the AR System server and BMC Atrium CMDB.
3. Prepare the AR System server before you upgrade BMC Atrium Core and other BMC applications The BMC Atrium Core installer prompts you to enter information about the AR System server.
4. Perform procedures to improve the upgrade performance of BMC Atrium Core After you upgrade the AR System server, perform these procedures to reduce the time required run the installer for an upgrade.
Perform the upgrade
1. Perform the BMC Atrium Core upgrade

This procedure installs BMC Atrium CMDB, Reconciliation Engine, and Normalization Engine.

You cannot install BMC Atrium CMDB on a remote AR System server; you must perform the installation on the computer on which BMC Remedy AR System is installed.

Postupgrade procedures
1. Validate the upgrade
  • Review the log files
  • Create a zip file of the logs by using the maintenance tool
  • Perform a health check
2. Review the upgrade log files The installer writes status messages to a log file, giving a detailed account of all changes made to your data model during the upgrade. If the upgrade fails and you must run the installer again, the installer resumes after the last operation it completed, rather than repeating operations that have already been completed.
3. Identify duplicate records The upgrade of BMC Atrium CMDB can result in duplicate records of the same virtual system. To identify those duplicate records, the upgrade installer launches a postupgrade utility called vzUtil.
4. Enable entries in the armonitor and ar configuration files Enable the entries that you commented out before the upgrade.
5. Delete obsolete directories after upgrade

When you upgrade from version 7.5 or later, you must choose a new installation directory for the upgrade that is not below the BMC_AR_SYSTEM_HOME directory. 

The old installation directory is now obsolete and should be deleted to avoid confusion. 

6. Clean up normalized CI relationships The datamig utility cleans up the configuration items (CIs) in the staging datasets for which relationship names are normalized following the old best-practice relationship rules, and impact relationships are generated following the old best-practice impact normalization rules.

Upgrade BMC  Atrium Core Web Services 

Step Action Additional Information
1. Perform BMC Atrium Core Web Services upgrade
  • If you have installed the earlier version of BMC Atrium Core Web Services on a separate computer, upgrade BMC Atrium Core Web Services on that computer after you have upgraded BMC Atrium CMDB on the primary stack.
  • If you have installed the earlier version of BMC Atrium Core Web Services on the same computer on which you have installed BMC Atrium CMDB, BMC Atrium Core Web Services is upgraded when you upgrade BMC Atrium CMDB.

Upgrade BMC Atrium Integrator 

Step Action Additional Information
1. Perform the Atrium Integrator server upgrade

To upgrade from 8.0 to 8.1: Before running the Atrium Integrator server installation program, set Max Attach Size in the AR System Server Information window to 0 MB or 100 MB. If Max Attach Size is set to a value other than 0 MB or 100 MB, the Atrium Integrator server installation does not complete.

To upgrade from 7.6.04 to 8.1: When you upgrade Atrium Integrator 7.6.04 to 8.1, a backup of your old jobs and transformations is created and saved to the ARSystem directory. The upgrade then proceeds like a fresh installation. The backup might complete or fail at times, depending on which you may need to perform additional tasks in case of failure.

Stage 6: Perform the post-upgrade steps 

Step Action Additional information
1. Reconcile customizations When you upgrade applications or system components, some objects that you have overlaid might be deleted, which means that your overlay is deleted, as well. Similarly, some of your customizations might interfere with the upgraded behavior. You must reconcile these customizations before using the application.
2. Rebuild join forms that were deleted before an upgrade
3. Identify and correct invalid field mappings in join forms When you upgrade the BMC Remedy ITSM suite, if the installer detects invalid field mappings, you can refer to the CIDataMig.log file to identify the forms and fields that require correction.
4. Rebuild customizations before deleting BMC Remedy ITSM suite attributes from the BMC Atrium CMDB
5. Rerun the Prefix Manager in Hub and Spoke environments If your system is configured for a Hub and Spoke capability, after you perform an upgrade to your BMC Remedy ITSM suite on the Hub and Spoke servers, you must rerun the Prefix Manager as described in the procedure.
6. Update BMC Remedy Knowledge Management for popular articles

BMC Remedy Knowledge Management version 8.0 and later includes an integration with BMC Service Request Management that displays the most popular articles in the Request Entry console.

By default, popularity is calculated only for articles created in versions 8.0 and later. To include pre-8.0 articles in popularity calculations, run two escalations as explained in the procedure.

7. Perform the database backup
8.

Perform feature and functionality validation and performance testing

9.

Restore the backed-up, upgraded staging server database after the testing is complete

10.
