For the migration you will need 2 new storage domains - one for the HE and another for the VMs.For the VMs it's simple, while for the HE you will need to backup and then restore on the new volume.

The hosted engine runs on a nfs storage type. In this environment runs twelve VMs (thirteen if we include the self-hosted engine). So, now I have the urgency to do the following activities: 1) Migrate the hosted engine storage from nfs to fc (I have now an fc storage on this host). 2) Upgrade the ovirt to 4.3 release. So, I would like to have your help to understand how to implement the above two steps in this particular case ( one host and the self-hosted engine ).
