Situation:
Need to upgrade Redis 3.2 to the latest stable version in a 3 server and 3 sentinel architecture with a plan for rollback to the previous state in case of any issue without data loss and downtime.
Findings:
Rollback is problematic because the RDB version mismatched as 3.2 uses RDB 7 and doesn't support RDB 9 which is supported by the newer versions. Now, under this, there are 2 problems.
Also, any other heads up with this upgrade/rollback is more than welcome as well!
Thanks in advance. :)
