Normally it's easier to create the cluster on the existing node already in use.
As on cluster create nothing gets lost, but when joining a cluster we start with
a fresh cluster filesystem.

But normally you can save /etc/pve/nodes/NODENAME folder and optionally
storage, firewall, etc. configs of your existing node, add it to an existing
cluster with '--force' and restore the VM configuration files and merge the
storage, firewall, etc files.
You just need to ensure that there will be no VMID conflict...
