I currently have MongoDB version 3.4 with sharding implemented, and I’m interested in upgrading it to MongoDB version 7. Could someone please provide me with a list of the required patch version upgrades to reach a stable version? My intention is to perform this upgrade through a rolling update process.
Thanks in advance.
As of today:
3.4.x → 3.4.24 → 3.6.23 → 4.0.28 → 4.2.25 → 4.4.28 → 5.0.24 → 6.0.13 → 7.0.5
The starting point after the installing the lastest minor version of 3.4 is:
https://www.mongodb.com/docs/v3.6/release-notes/3.6-upgrade-sharded-cluster/
Then the same “Upgrade Sharded Cluster” in the release notes for each Major Version in the path above.
