I am facing a big issue restoring the backup on CRS326 which I previously made on CRS125,
Right now CRS125 is redundant therefore we immediately needed to replace it with another router which happens to be CRS326,
The problem is when I restore the backup of CRS125 on CRS 326 I cannot access the router in any way even though I know the password and weirdly all the port leds don’t light up,
Obviously the backup works as I can see it through the Winbox got the exact IP and all but for some ambiguous reason can’t connect to the admin panel.
I suspect it has something to do with MAC adress because after the backup it gets the old router CRS125’s MAC adress.
To add to what @xvo wrote: backups between different device models are definitely not compatible. Backups are binary blob which, upon restoration, doesn’t check for e.g. interface availability, switch-chip capabilities, etc.
Restoring backup on diffefent device of exactly the same model might work, interface MAC addresses will be a mess but the rest will likely be fine.
You can’t selectively restore parts of backup, it’s “all or nothing”.
The best bet would be to get (borrow) another CRS125 (the same model you had), backup its configuration, restore it from your backup, export configuration to ASCII export file and restore it to original configuration (from backup made on the beginning of this paragraph) to return it in same working condition.
