I had a Mikrotik router which was a bit old and it went bust. Fortunately I still have the configuration file for it.
Is it possible that I upload this configuration on a new router and it works? without having to reconfigure it from scratch? I understand that configs are different for each model but is there a utility or a website which can convert the configuration from that of a model to another?
yes you can restore your previous router backup in new router very easily. let me know your previous router OS version ? you might face little problem if your previous version router OS and new router OS version far different.
Oops this router os version is very old, if you restore this backup to new router os then You might face some problem. Better try to take backup using export command then check syntax and update the script as needed then import to new router.
open the exported .rsc file using notepad. copy single command and put it on new router OS, if it don’t give any error messages then you are fine with that part. step by step you check all configuration.
like /ip firewall filter
if one command work then if there are next one hundred firewall filter rules also work.
then check /queue
copy and paste one command in new router os, if you get error in syntax then check the new router OS version syntax and edit our old syntax accordingly using replace command in notepad.
