I'm wondering if anyone have a best practice advise for it to do that replacement without service Interruption.

Not sure what will happen when changing the Master Stack note in case of mLAG, as the MLAG MAC is changing. Anything else I need to think about?

If you reconfigure the mlag lacp-mac you will get a short outage yes.

ok, but I think when changing that one, on master and backup Core, there will be an interruption?

If you configured the stack mac address and MLag lacp mac-address no mac-address will change.

configure mlag peer lacp-mac
