I'm preparing to remove the installed N55-DL2 layer2 I/O module from my 5548UP switch and install a N55-D160L3-V2 layer3 I/O module. Do I lose any of the switch config or is that stored in a location that is not on the N55-DL2? I have the licenses I need (including the infamous LAN_BASE_SERVICES_PKG license). I also have the install guides in hand and I'm putting together the design and task list. I'm working on getting access to a lab 5548UP, but in the meantime I'm doing as much homework as I can. thanks!
