Config From RB750 to RB951G-2HnD

Hello.
Just buied a RB951G, how corectly i can migrate the config file from 750 to 951?
I made a Backup (750) - Restore (951). And the ports are not like need to be. On 951 after restore port 2 is 4. Gateway 1 is doesnt exist, and the MAC adrres is like on 750.
What shoul i do to correct restore the config file?

Run /export or /export file-name=config on your old router. Download file to your computer, review configuration and upload to new router.
You can upload file or copy line by line to router, and get better control over the process.

Thank you! That works!
