Hi Sokratis, You can go to Data Center main tab, choose relevant DC, click right click on the DC, choose 'Re-Initialize Data Center', in this window you can choose another compatible Storage Domain and choose him to be your master Data Storage Domain.

Is there a way to manually change the Master Data Domain? Will the Master Data Domain be reassigned automatically when the current one is deleted?
