Password lost after transferring startup-config

Engelsit

Hi. I want to transfer my settings to new Keenetic device. 
From Giga2 to Ultra. 

I am saving old settings to file. Then i Uppload it to new device. Everithyng works very good, bit my old admin password does not work. I made a new user at old device with empty password. But still cannot enter. 

How can I delete password from settings file or make it compatible with new device? 

Thank you. 

P.S. I still have both devices, and can do everithyng.

1. I made a factory reset at new router.
2. Press "do not create password" after start
3. Save settings to file
4. Found hash of empty password "    password nt 68dc5c2dXXXXXXXXXXc504f744a7ab04"
5. Copy found hash to the settings file of OLD router.
6. Upload modified settings to new router
7 Yeah! 

Then, i found some initialize strings for 5gHz AP. Everything works fine now!
