I have been using an RB493G router for a long time as the main router in my lab testbed. I ran out of ethernet ports so I purchased the new CRS125-24G-1S-2HnD-IN. Is there a nice way how to migrate the configuration from the old router to the new one? I have tons of NAT entries, static DHCP addresses, wifi access rules, etc. in the old one and it would be a pain to re-type everything.
I usually export the running configuration to a file:
Log into terminal on your exisiting device
Run the command export file=config.cfg
Copy the config.cfg file to your computer(drag and drop from winbox)
Open the file on your computer
Past the configuration lines you want into the terminal of your new router
Maybe there are easier ways, I dont know. But this has always worked for me. You also have to be a little carefull, since you are swapping to a different model, and you may have to adjust your interface parameters.
