I would like to ask you a question

I have an ovirt 4.4 which got corrupted certs and I can't access the gui. It gives me error 500 internal when I want to access.

I have a new ovirt 4.5 on glusterfs which I would like to migrate all my vm's to.

Is this possible? Can it be done by cli? It would save me from having to reinstall all the vm's.
