MongoDB 5.0.0-rc2 is out and is ready for testing.
This release candidate requires extra steps when upgrading a sharded installation from 5.0.0-rc0 or 5.0.0-rc1.
Note: Only installations which have all these conditions need these extra steps:
- mongod/mongos is running 5.0.0-rc0 or 5.0.0-rc1 AND
- Feature Compatibility Version (fCV) is set to "5.0" AND
- The deployment contains sharded collections
To upgrade from 5.0.0-rc0/5.0.0-rc1 to 5.0.0-rc2 the following procedure must be followed:
- Downgrade fCV to "4.4"
- Upgrade binaries to 5.0.0-rc2 and set fCV to "5.0"
To downgrade from 5.0.0-rc2 to 5.0.0-rc0 or 5.0.0-rc1:
- Downgrade fCV to "4.4"
- Change binaries to 5.0.0-rc0 or 5.0.0-rc1 and set fCV to "5.0"
As always, please let us know of any issues.
