Are you trying to convert (P2V) a physical server into a VM and then after
repurpose the same server into a standalone PVE host?
If so, then definitely it won't be quick, especially without some kind of
shared storage.

You could potentially reduce the time needed by following these steps...

- P2V your physical server into a VM at your test PVE cluster.

- Shutdown original server and then start its VM version on your test
cluster. Leave it running there for some days and see if everything
is working properly.

- Repurpose original server into a PVE host but do _not_ add it as a new
cluster member on your test cluster. Just connect it to the same physical

- Start copying the running VM onto this standalone PVE host. You could use
rsync for example or zfs send/recv if you are using ZFS at both sides.

- Once transfer is finished,  shutdown the VM on the test cluster and then
immediately do a final rsync or zfs send/receive so that the latest changes
are replicated on the target server.

- Create a new VM on standalone server and attach the VM disk onto it.

- Start the VM on standalone server and delete it from your test cluster.
