Upgrade Leaves the Application in a Broken State

Fix problems that appear immediately after applying a CAST Imaging upgrade.

Symptom

After upgrading CAST Imaging:

  • The interface does not load (blank page or JavaScript error).
  • Applications do not appear in the list.
  • A specific feature that worked before now gives an error.

Step 1: Clear the server-side cache

A stale cache is the most common cause of post-upgrade problems.

Step 2: Verify the Neo4j schema

After a major upgrade, the Neo4j schema may need to be updated.

Step 3: Re-import applications

If applications do not appear after the upgrade, trigger a manual re-import.

See Import application data into Imaging.

Step 4: Check the upgrade logs

Review the upgrade logs for errors.

Step 5: Roll back

If the issue cannot be resolved, restore from the backup you took before upgrading.

See Back up and restore.
