Hi!
I am having problems, absurds problems, for restore config from RB2011 with 6.36 version to RB1200 with the same version. Restore file config is ok, RB1200 reboots..and i cant access for any ports, and don’t answer for the ips for each ports.
I have made this process three times with same result.
Any idea ? what is that escapes me ?
Thanks
You cannot restore a backup from one device onto another, not even when it is the same type.
Oh shit! i’m on a newbie error!
i’m forgotten that I must use export instead of backup
A lot of thanks, i had been a lot of hours nodding off with hard wall 
Even the import of exported config will not work correctly when imported untouched. The devices are physically different so the config will not fit. You need to adjust it accordingly before import. Don’t forget to have the same ros versions and the same packages installed on both devices before.
It might work if both units are similar, and port number is similar. I suggest opening the file and editing out unneeded stuff, or just to check what will be imported. It is in human readable format.
It is a bit tricky. I recently tried this method to copy a config from one router to another of exactly the same type (RB951G-2HnD).
I edited the .rsc file to have the correct IP addresses for the new router, and also the correct MAC addresses (obtained from an export of the target router after default config).
I also made sure the software version and the installed packages on the new router were the same.
Then I did a “reset-configuration” with “no default” and “run script”, and specified that exported config that I uploaded to the new router.
Could not get it to work. Extremely frustrating is that you cannot see why and where it fails, and the import just stops at the first error.
When there is an error and the router is not reachable on the LAN ports, there is nothing you can do to debug it.
I opened an issue for it [Ticket#2016072166000671] and suggested that the import continues after each minor error and writes a log file
so that you can see what went OK and what not. Hopefully it is implemented…
Transferring config from one router to another or from a single base config to a number of new routers is something that really comes in handy
when deploying or sometimes when doing a migration.
I got it OK by cutting and pasting a few lines at a time into a telnet window, carefully deleting the default config at the correct moment,
but it took more time than I hoped. We irregularly buy new routers that I need to process the same way.
(as I never found a problem in the rsc, I still think the reset-to-default config is somehow broken, I used it before on another router
around version 6.30 and then it worked fine)
