Copy App Stacks to Another Environment

Hello,

I'm trying to copy some of our productions App Stacks to our new UAT environment. There is no shared storage between the two environments. I'm trying to use the process in the following KB. Using WinSCP I can upload the *.vmdk, *.vmdk.metadata, *-flat.vmdk files but they become thick provisioned. I tried using vmkfstools -K AppStack_Template_Name.vmdk to convert it back to being thin provisioned but I get an error "Not a supported filesystem type" If I try to manually attach it to a VM I get a error in the vSphere console " VMDK cannot be opened for writing. It might be shared with some other VM". I'm think the vmdk or flat file is corrupting, but I'm not sure. I can't figure out what I'm doing wrong.

Does anyone have any other tips for copying App Stacks?
