The Upgrade Assistant screen is accessible by logging into the Web Console and navigating to [Manage→DPOD Health→Upgrade Assistant].
Some DPOD versions include new versions of the Store engine, which might require some of the existing data to be reindexed to a newer format or structure. The Upgrade Assistant prepares the DPOD instance for upcoming upgrades by reindexing data in the background (if required) while DPOD is up and running.
The screen shows contains three sections:
- Upgrade Assistant - Showing whether the DPOD instance is ready for upgrade or not.
- Reindex Options Options - Showing configuration details that determines the reindexing process behavior.
- Reindex Status Status - Showing Showing a detailed status of the reindexing.
