This document provides the procedures for upgrading or migrating to Avaya SBC Release 10.2.1.
To upgrade to a new release of Avaya SBC, there are two distinct processes you can use:
Standard upgrade process
Migration process
The standard upgrade process has limitations for certain deployment types, and if your deployment type does not allow the standard upgrade process, you must use the migration process. The migration process is more universal and can be used for any deployment type, even if the standard upgrade process might work.
Caution:
Doing an upgrade or migration on your system is service affecting. Plan upgrades or migrations for a maintenance period or when there is no traffic or during a low traffic period.
You can upgrade Avaya SBC in two ways:
You can do an in-place software upgrade reusing the existing hardware or VMware servers.
You can migrate data from an old Avaya SBC system to a newly-installed Avaya SBC system.
A key advantages of using an upgrade procedure is that:
You can start the upgrade from the web interface.
You do not need to install the system with the release to be upgraded which sometimes requires manual intervention.
This document also includes procedures to roll back an upgrade or migration.
