Need to disconnect nodes from switch one by one

due to maintenance I need to reboot one switch.

I have some nodes of a cluster connected to it for two networks, wan bridge and cluster network (not storage).

If I am right a short disconnection from wan should not cause troubles, and Linux lxc should manage reconnections.

What is the best practice before disconnecting cluster net cable of a node from switch (to move cable to a backup switch one node a time)?

Do I have to stop any service or run any command before and after disconnecting/reconnecting?

I hope I do not need to shut down each node twice (forth and back).

Thank you.
