Db2 version migration and fallback

When a Db2® subsystem that is being used with Db2 Automation Expert is migrated to a later version, or must be reverted to a prior version, follow these steps.

After your subsystem has been migrated to a later version of Db2, you can port your repository statistics to the new subsystem. For example, you can port the statistics repository from a Db2 12 subsystem to a Db2 13 subsystem. Information about migration is also provided in this topic.
