DiskExtender Migration from Centera to ATMOS issues

We have vendor migrating from Centera to ATMOS using Disk Extender. The migration works but continually gets intermittent errors below whcih they fear slow it down. DAta is fine once on ATMOS.

Running DX 6.5.0.440 SP3 path 1

Centera 4.1.0-3672-1-0

ATMOS
