    Description

      Under MMAP, there's a limit on the generated index namespace in a collection due to the on-disk format. This constraint imposes a restriction on the target collection namespace when we are doing collection renames. It's likely that this constraint may not apply to WiredTiger.

      This may have implications for importing databases between different storage engines and also for downgrade to previous versions of the server that still have this restriction.
