Environment

AEM 6.0 or 6.1 upgrade to 6.3 or 6.4

Cause

The AEM upgrade does not update the index definition automatically.

Resolution

  1. Go to http://aem-host:port/crx/de/index.jsp and log in as the admin user.
  2. Delete /oak: index/lucene index.
  3. Restart AEM.
  4. Monitor the logs for indexing of the new /oak: index/lucene index.

Nota:

Indexing does not take many hours. However, it is required for the successful upgrade.
