We are doing production deployment ande I have tested 3.12.4 and found okay
to proceed. But we have decided to use tiering feature at the last minute.
But something is not right or missing with tiering feature in 3.12.4 and
hence, I'm thinking of using higher versions which may have fixed bugs with
tiering. But we don't have enough time to test it completely for other
possible issues for production deployment. So, I'm checking for a safest
version with stable tiering feature.

Consolidating the files to a backup storage and restoring them is not
efficient or feasible option for us, as we have terabytes of small file
data which can take huge times..so, downgrading or upgrading is something
we can't do so often but only with a scheduled downtime. Hence, trying
version 5 and falling back is not preferred option for us.
