Thanks for your help so far.

The procedure you describe seems managable for us:
(in short)
- Prepare new server (install, configure and test OS and LON-CAPA)
- Transfer data from old to new server
- Shut down/Disconnect old server
- Activate new server

One question left concerning the hostname, DNS name and IP address:

The old server should not be seen again in the LON-CAPA cluster, but the
new one. The new server needs to have a new DNS name AND a new IP address.

Is this possible?
