Hey @dogs_Cute ,

Quick follow-up question , on the “copy the data directory” method since looking online I see mixed suggestions.

What specific files in the source data directory should be copied ?

All *.wt files (all collection & indexes, or only some collections). Also WiredTiger, WiredTiger.turtle, WiredTiger.wt, storage.bson, etc ?

Is there a specific rule or just copy everything ?

Thanks a lot.
