Hi
Did you try to copy the template to the new storage domain?
Under Template tab -> Disks sub-tab -> copy

Hi,
I have a data storage domain that use one FC LUN. I need to move all
    data to a new storage server.
I tried by move single disks to a new storage domain but some
    cannot be
    moved, I think because they are thin-cloned by template.
When I worked with LVM I use to do a simple pvmove leaving the VG
    intact, is there something similar (online or in maintenance) in
    oVirt?
    Can I just do a pvmove from the SPM host o it's going to destroy
    everything?
Thank you very much.
Regards,
        Dael Maselli.
