ESXi to PVE migration

[casalicomputers]

Hello everybody,
I'm planning the migration from our current virtual environment from VMware ESXi 5.5 to Proxmox.
I need to migrate VMs from main server to a temporary server, install proxmox on the main server, and then move VMs back in there.

Since now I have a FC-SAN available, here's what I would like to do:
1) Install PVE on temporary server
2) Create a RAID10 volume on the SAN and export a LUN
3) Attach the SAN LUN from the temporary server and create LVM partition on it for storing VMs data.
4) Migrate all VMs from ESXi to Proxmox
5) Shutdown ESXi host, reinstall it with Proxmox and reconfigure network and storage.
6) Reconfigure VMs on the new host
7) Shutdown the temporary server.

At point 6: How do I migrate VMs from the temporary host to the new one? Is copying config files from /etc/pve/nodes/nodename/qemu-server to the same path in the new server enough? (after, of course, have reconfigured network and storage the same way as the temp node)

I would like to avoid creating a cluster just to move vms from an host to another...

Thanks

Hi,

Your approach is correct,
but you have to be very careful that you do not start a vm on two nodes at the same time,
this will destroy you vm image.
I would turn off the temp sever, before add the storage and copying the config files in the main server.
