Hello,

We are decommissioning a storage array and I would like to move the existing ISO domain to another array. Is there a Move or Migration function for ISO domains? I attempted to create a new ISO domain however that option is not available in the drop down menu. We are running version 3.5.0.1-1.el6 (yes - I know it's old - but it works for us :-)

We support moving disks between storage domains, but this work only for data domains.

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.../
