Thank you for asking this question in the support community. If you are going to physically move the ADTRAN unit to another location (with separate configuration settings), then I recommend you save the current configuration to a computer or server and then load it back on the ADTRAN unit when you replace it. To do this in the web interface navigate to the following: Utilities > Configuration > Download.This will save a copy of the current configuration.
Then when you are testing at the new location, you are correct, typically you should only have to change the IP address/subnet mask and default-route next-hop IP address at the new circuit. Then when you go back to the original location, you can simply load the "old" configuration back on the unit with the following steps: Utilities > Configuration > Upload Config: > Reboot Unit (do not save before rebooting).
I hope that makes sense, but let me know if you have any questions.
Perfect sense, thank you!
