Re: [Users] Documentation: Storage Domain conversion from Data Domain to Export Domain

Hey All, I ran into this issue myself where I needed to convert a data domain to an export domain in order to recover virtual guests from a corrupted ovirt/rhevm instance into a new ovirt/rhevm instance. This wasn’t documented anywhere that I saw but with the help of Itamar Heim and an well timed email to the list from Igor Lvovsky last night I was able to do this and wanted to send to the list a documented procedure for how to modify the metadata of the data domain prior to import as an export domain. This procedure works for both RHEV-M and Ovirt. Let me know if you have any questions.
