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.</div><div dir="auto"><br></div><div dir="auto">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.
