However in current version (4.2), you can upload ISO images directly to data domain of any type, so you don't need the ISO domain or NFS in your FC/iSCSI based setup. To copy the ISO files from the old ISO domain to data domain on new storage, you can: 1. upgrade to 4.2 2. mount the old iso domain on some machine, best one of your hypervisors 3. upload the ISO files from dom-uuid/images/1111.../* to a data domain using ovirt SDK[1] If you want a simpler solution, maybe keeping 3.x: 1. detach the old ISO domain 2. add new empty ISO domain on another server 3. mount the old ISO domain on one of the hypervisors 4. rsync the images from old domain images/111.1../ dir to new domain images/1111.../ [1] https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload...

You have to put into maintenance and detach, before you can create and add a new ISO domain.

If you have a block based storage domain you cannot done it because of this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1589763

And it doesn't work where probably would be more useful, avoiding so NFS if not already in use for other reasons. Created in 4.2.3 but always shifting the solution... even if both priority and severity have been marked as urgent: I suggested to decrease them if there is no plan to solve in short time actually...
