We are running into an issue where SSMove is now expanding Thin disks into Thick again. Although this didn't happen previously on LM 4.0.4, just today I used SSMove to move some items with thin disks and the disks are now thick provisioned on the destination LUN. We have run updates on our ESX hosts since the last time SSMove was moving thin disks and retaining them as thin. This is the only environmental change I can think of. Could is be possible that an ESX code upgrade changed this behavior? We are running version 4.1 build 1682698.
