Description Germano Veit Michel 2019-07-25 04:52:17 UTC
Description of problem:

When transferring VMs between Data-Centers, customers are advised to use Data-Domains since Export is deprecated.

However, when doing the transfer between different DC Levels, the floating Data Domain may get upgraded (i.e. V3 to V5), which can prevent it from attaching back to the source DC to transfer more VMs. Making the floating Data SD one way only.

For example: 
  Source: RHV/DC 4.0 with V3 SD
  Destination: RHV/DC 4.2
  -> Once the Data Domain is attached to Destination it is upgraded to V4 and it
     cannot be attached back to the source.

So please add a warning asking the user to confirm that the import will upgrade the Storage Domain to Version X, explaining that it may not be able to attach back to the older RHV DC and that if that is required the user is encouraged to create a new data-center in the destination with the same level of the source, and then bump the DC level once the transfers are complete.

Note there already is a similar problem with Cluster Level. And another one when importing a VM to newer CL the VM is not correctly updated
