      Hi,

      We are looking at moving hypervisors to a new pool due to a license constraints.
      Currently we have 6 in the pool and we need to go back to 3. However, we have 3 VMs running on local storage on the each one of the hypervisors which we need to move out. Since all data about the storage and VMs is stored in XO's database, we are wondering what would be the best option to do that.

      Current plan is to:
      Shutdown VMs.
      Forget the local SRs.
      Remove hosts from the Production Pool and create a new pool.
      Re-import SRs.
      Re-import VMs.

      Would this work, as I'm not sure about the re-importing bit, in case the SRs need to be clean/empty.
      Is there any other way ?

      We can't do a backup/restore of those machines, or replication.

      Thanks,
      H

        You might want to elaborate on this because those are probably some of your best options.

        What about migration?

          Each VM has 2x4TB SSDs passed through which are stitched with LVM inside the VM. We don't do backup or replication of them historically due to the size of the disks.

          We can't really migrate them elsewhere.

            Those are important details. Are you running Windows VMs?

              Yes, I'm sorry I thought I wrote them but I've only said local storage where I meant local storage and pass-through disks ....

              Nope, they run on Debian.

                license constraints.

                Please tell us more about these.

                Hopefully you will receive some additional input from someone more familiar with passed through disks.

                  The 3 hypervisors that we need to remove from the pool are old and have been replaced by 3 new servers. Everything has been migrated to the new hypervisors and those 3 are only running 1 vm each with a passed-through disks.
                  We have XCP-NG licenses for only 3 of the hosts, so we were looking at moving out the old hosts into a separate pool which will remain unlicensed.
                  Eventually, those 3 VMs will be turned off but we need to keep them running for few more moths (if we're lucky).

                    I would suggest using your existing support mechanism to obtain advise on the best way to achieve your desired outcome.

                      Yeah, I was going to but wanted to put it as a discussion with other people. Maybe someone else has had similar situation.

                      I'll open a support ticket now.

                      Thanks.
