Staging environment implementation for upgrade

The staged-upgrade process allows you to upgrade your application and create overlays or otherwise address pre-existing customizations to your BMC Remedy AR System server objects while your production server remains available to users.The following topics are provided:

Servers that might be required to perform the upgrade

The following illustration shows the set of servers that might be required to perform the upgrade:

Staging server implementation

For setting up a staging environment, use either of the following methods:

Accelerated staging server:

  1. Copy the production server database to the staging environment.
  2. Upgrade BMC Remedy AR System server.

For more information, see Setting up an accelerated staging server

Duplicated staging server:

  1. Duplicate the production server.
  2. Copy the production server database to the staging server.
  3. Upgrade BMC Remedy AR System server. 

For more information, see Setting up a duplicated staging server.

Keep the following considerations in mind when upgrading using a staging server:

  • Whether you use the accelerated staging server setup or the duplicated staging server setup, you must copy your entire production database to the staging server.
  • At the end of the process, the staging server becomes the new production server.
  • Ensure that the staging server you use meets the specifications required for the upgrade. For more information, see System requirements.

Note

When you create the staging server, use the same server IP address as used for the production server, to avoid integration issues when you promote the staging server to production.

Also, after you change the host name, follow the process outlined in Changing a server name when using a duplicated or migrated environment  in the BMC Remedy AR System documentation. 

Reference server and upgrade reference server implementation

If you are implementing the reference environment, you might require another server (referred to as the upgrade comparison server) to host upgraded applications. These additional servers do not have to be production quality, but they must have compatible software and a compatible database to hold referenced copies of the BMC software and database objects. The reference server and upgrade comparison server are temporary servers and are not needed after the entire upgrade process is complete. 

This version of the documentation is no longer supported. However, the documentation is available for your convenience. You will not be able to leave comments.
