Swap 9300-48P for 9300-48UN easily in stack?

[stonent01]

Lets say I have a stack mixed with 9300-48P (Gi ports) and 9300-48UN (Fi ports) and want to swap a few 48Ps out with 48UNs.  Is there an easy way to accomplish this?

Something like telling the stack, hey I'm about to remove switch 3, and whatever switch comes back in, transfer the config over and take the same number.

Or do I just need to do it the hard way and copy the Gix/x/x configs and replace Gi with Fi, then pull the Gi switch, put in the Fi switch, paste the configs and then renumber it?

The situation being I need to reuse the 48P switches that are currently in some deeper racks in some smaller racks where the 48UN's won't fit.

Hello @stonent01 ,

if the interface naming is different as described also in the command reference in the following link:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/17-14/command_reference/b_1714_9300_cr/interface_and_hardware_commands.html#wp1695551075

I'm afraid it is not easy to change a member from Gix/x/x to Fix/x/x or viceversa unless the stack master is so smart. (I don't think so)

I would suggest you to build a test rack made of a mix of models and to test on it the change of provisioning of a member switch and to see what happens.

I ended up just copying the port config and doing a search and replace on GigabitEthernet to FiveGigabitEthernet for that switch.
Then I pulled the switch out "live" and then deprovisioned it. The new 5GB switch went in and took the old switch number and then pasted in the new config.

Most fortunately that switch had almost no ports in use,
