Migrating from 3.30.0, 3.30.1, and 3.30.2
The Sourcegraph 3.30 release introduced a change that caused corruption in certain indexes, breaking a number of Sourcegraph features. This issue affects Sourcegraph 3.30.0, 3.30.1, and 3.30.2, and was fixed in 3.30.3.
- Users on 3.29.x are advised to upgrade directly to 3.30.3.
- Users that have already upgraded to one of the affected releases must fix the already corrupt databases manually by following this guide: How to rebuild corrupt Postgres indexes.

However, this means that after fixing the corrupt indexes on the alpine images in the affected releases, upgrading to debian based images in 3.30.3 will cause index corruption again. For this reason, do not upgrade to 3.30.3 after fixing corrupt Postgres indexes. Instead, please upgrade directly to 3.31.
