[ovirt-users] update to 4.4 fails with "Domain format is different from master storage domain format" (v4.3 cluster with V4 NFS storage domains)

Hello, I'm trying to update our hosted-engine ovirt to version 4.4 from 4.3.10 and everything goes fine until hosted-engine --deploy tries to add new hosted_storage domain, we have NFS storage domains, and it fails with error: [ INFO ] TASK [ovirt.hosted_engine_setup : Activate storage domain] [ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Domain format is different from master storage domain format]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Domain format is different from master storage domain format]\". HTTP response code is 400."} It looks like storage domains in data center should have been upgraded to V5 when DC and cluster compatibility version was updated to 4.3, but looks like it was implemented in ovirt 4.3.3 and this setup was updated from 4.2 to 4.3 before 4.3.3 was released, so I ended up with 4.3 DCs and clusters with V4 storage domain format. Is there any way to convert V4 to V5 (there are running VMs on them) to be able upgrade to 4.4? --
