@<1736194540286513152:profile|DeliciousSeaturtle82> the data folder for mongo4 and mongo5 might be slightly different. What is the target path where you're moving data in mongo5? And how is that mounted?
And when you say "broken", could you elaborate on that? Does the target Mongo Pod crash when trying to move the data? Or you succeed in copying the data but can't see the result in the UI?
