OpsManager upgrade 5.0.17 -- 5.0.21 -- 6.0.17

[chris (Chris Dellaway)]

You should open a support case with MongoDB and have them review the Ops Manager deployment and guide you through the upgrade.

When I update opsmanager to version 5.0.21 and then to 6.0.17, is its system database (AppDB) automatically updated?

AppDB is something you will have to upgrade manually. You can monitor it with OpsManager but it should not be managed by it.

Or must I first update the mongodb verion of the AppDB database and then proceed to update opsmanager?

Ops Manager 6.0 requires MongoDB 4.4 or later for the backing databases, 4.4 is deprecated. But yes updating your backing db should occur first.

Roughly you should.

1. Consider taking a dump of the AppDB
2. Upgrade the AppDB 4.2.13-ent → 4.2.24-ent → 4.4.23 → 5.0.19-ent
3. Upgrade Ops Manager 5.0.17 → 5.0.21 → 6.0.16
4. Upgrade the AppDB to 6.0.8-ent
