CRS125-24G-1S-RM vs CRS326-24G-2S+ BackUp

Wed Nov 06, 2019 9:52 pm

Greetings Mikrotik community,

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.

Hope someone can find a solution.

Backup is not meant to be used on any other device, except for the one it was made on.
Use config /export for that.

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.

Thank you both to narrow it down for me,

But the thing is I can't access the old Router anymore so that I can use export command. The only thing that's left is the backup.

How can I only take the configurations from this BackUp to prevent applying a specific identity of the previous router?

Thanks,

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.

Can I set up the RouterOS as a virtual machine on EVE-NG or GNS3 and restore it in there?

Would it work?

ROS in a VM would be "device" model CHR ... which is, again, not the same as your original device.

I'm affraid that the only way to get exported config is the way I already described.
