I had a previous default config file that I used to flash the routers, until recently when trying to restore the backup file on a new router I got the information that the backup file was not compatible with teh fevice.
After analysing, I saw that the part number was different between each other, ending up with RUT2400DE000 and RUT24006E000.
My question is, is there a way to still import configs between different router part numbers, or will need indeed 2 backup configuration files?
The devices have different product codes and the hardware is slightly different (the modem versions). Thus, you receive an error when you try to upload the backup. I would suggest following the method outlined in the previous response (copying configuration files).
