You should maybe change the RRD-files to read-only or modify the housekeeping-script, otherwise housekeeping will delete the RRD-files when they are unchanged for 30day or whatever the default is.

The way I handle this is to rename the old router, disable it, and then
add the new router.

You can't really retain the information and delete the device, so you
can just disable and rename it, and then delete it in a year or so when
the data isn't useful anymore.
