Backup/ Restore issue and duplicating Ethernet MAC address

RouterOS General
1

Dear all;

Greetings;

I am asking about the backup restore procedures, I got an old Mikrotik hardware, and I want to replace it by newer, the issue is I didn’t know when you are bringing in new hardware to your network using a restore configuration from the same old hardware inside the network you are actually making a problem for your self! because the new hardware will take the “same” Ethernet MAC addresses of the backup one! I am asking here, is that reasonable? is there any method to avoid this situation?
I don’t know maybe I am not aware of that except presently, but if you don’t use the “reset MAC address” for the all Ethernet of the new hardware, then same Ethernet MAC address will assign to the new Ethernet of the new hardware, I discovered that lately, that means if you not aware of this situation you will end up to have multi Ethernet ports of Mikrotik routers got the same MAC address in the local LAN, I am writing this hopefully someone correct me if I am wrong or I missed something here or maybe this issue had been discussed previously and I am not aware of it.

Suggestion: Backup improvements

I like to edit the text file before importing it. Avoids such problems and forces me to validate if config could be improved or not. And yes, this is normal behavior.

Backup file is meant to save and restore the configuration on the same device.

To migrate config to other devices, use Export and Import functions.

But why i do not see Import/Export in Winbox?

Those functions are not in the menu, that is true. Just open a CLI window and:

/export file=filename

As I suggested before, edit your file before importing it to the new router.

You could, technically, restore a binary backup to the new router (if same model), but you’d need to go through ALL physical interfaces and click on the reset MAC button to avoid the problem you described.

Again, the best, and safest option, remains export/import which isn’t too complicated.
