Hi, I have a problem that I need to convert our Dev environment to VLAN from GRE tunnels.
Can someone assist me on how complicated it is? the environment is about 10 nodes including compute, storage and control nodes.

There can be a LITTLE bit of downtime but not that much (hour, maybe 2?)
Is this even possible?


Thanks for any help, you can also contact me directly.

Best regards,
