Change from standard Timefinder Clone to Timefinder Clone Snap VP
I currently have a standard Timefinder Clone relationship in a "copied" state. I want to change this relationship to a Timefinder Clone Snap VP. After step 1 below the target tdevs are still going to have all the original tracks allocated. Do I need to unbind the target tdevs prior to step 2 or will the tracks automatically be unallocated when I create the Timefinder Clone with Snap VP session?
Steps:
1) Terminate Timefinder Clone relationship
2) Establish Timefinder Clone with Snap VP

You do not need to unbind and bind the target tdev prior to step 2, it will automatically be unallocated when you create a VP Snap with symclone -vse option
However, the following restrictions apply to VP Snap target:
Please see VP Snap consideration on page 7 from the implementing TimeFinder VP Snap white paper.

Hi,
Keep in mind that the symclone create –vse that needs to be done may take a longer amount of time. During this time, the extents related to the full sized clone are being released back into the pool and marked as free. Depending on the other pool activity this could take several minutes. So I would schedule the create process ahead of the activate process to ensure you have sufficient lead time. This only happens for a create that is essentially converting a standard clone to a VP Snap.
