Hello again!
I moved about 80 volumes now. All of them were volumes created by snapprotect (intellisnap). Everything worked fine. You can check whats going on in the background of volume moving, if you open the event menu of OCUM and set the trigger also on information. If you now sort by time you will see every volume move which is in progress and ther will be also information about the completion of it. Impact area for this events is "Protection". So you can see that OCUM will handle the connections for protection.
Regards
KFU
