The Upgrade Assistant screen is accessible by logging into the Web Console and navigating to [Manage→DPOD Health→Upgrade Assistant].
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 three sections:
- Upgrade Assistant - Showing whether the DPOD instance is ready for upgrade or not.
- Reindex Options - Showing configuration details that determines the reindexing process behavior.
- Reindex Status - Showing a detailed status of the reindexing.
Upgrade Assistant
The Upgrade Assistant section of the screen shows whether the DPOD instance is ready for upgrade or not.
The table below describes the possible Upgrade Assistant Statuses:
Icon | Description |

Reindex Options
This section shows the configuration details that determines the reindexing process behavior.
The configuration properties can be edited by clicking on the Edit button.
The table below describes the reindexing configuration properties.
| Detail | Description |
|---|---|
| Reindex Time Window | The period of time during which reindexing is allowed to run. Use the default reindex time window to allow reindexing without any time limitation. |
Number of Concurrent Tasks | The number of index sets (1-5) that can be reindexed concurrently. Increasing the number allows for faster reindexing at the cost of server resources, and may be used to get the system ready for upgrade sooner. |
Reindex Mode | The speed of each reindex task. Setting to "Intensive" allows for faster reindexing at the cost of server resources, and may be used to get the system ready for upgrade sooner. |
Reindex Status
