Hi Eugen,
Thanks for the advice. That helps me a lot :)

I just moved a (virtual lab) cluster to a different network, it worked
like a charm.
In an offline method - you need to:
- set osd noout, ensure there are no OSDs up
- Change the MONs IP, See the bottom of [1] "CHANGING A MONITOR’S IP
ADDRESS", MONs are the only ones really
sticky with the IP
- Ensure ceph.conf has the new MON IPs and network IPs
- Start MONs with new monmap, then start OSDs

I'm not sure where old IPs will be still visible, could you clarify
that, please?
Regards,
Eugen
