I have several old Datastores from which i moved all VMs via Storage vMotion to new Datastores. Now the VMs themself don't show any link to these old DSs anymore, but if you browse the DSs they still contain .dvsData Folders and .nvram Files.
My google search just showed that the .dvsData Folders contain data used for the distributed Switches and that the .nvram basicly contain the "BIOS". Also that .nvram will be created.
My question is, do i have to migrate these too? or are those just left over? will/are they newly generated with all current data or will something be lost because default settings are used?
On VMware vCenter Server 4.1
EDIT: for anyone intressted here is the KB-Article for acutally removing DSs in 4.1.
