Description

This reverts !190508 (merged) because the reindexing didn't succeed !190508 (comment 2504271245), and we don't want to apply this migration to self-managed. We have a couple of ideas to improve the reindexing: more logs and adjust cron worker timing, and we will try it again.

Related to #502817 (closed).
