How to move a subscription to a new server

[taurix]

Hi all, I'm managing a 5 node cluster with proxmox VE. I replaced two nodes because their hardware is EOL with a configuration with also 1 socket.

I shut down the old nodes, but I cannot add their subscription keys to the new nodes (it says invalid server id).

How can I move the subscriptions to the new node?

I forgot to mention that the new nodes have unique names, I did not reuse hostnames
