Export - Import profiles

Hello
I just bought a new PC.
I tried to move in one time all profiles from the old PC to the new one.
For this I marked all profiles and made a export. Then I reloaded this export file to the new PC.
Here I see the imported profiles, but the groups are build correctly, many profiles are outside of the configured groups!
Is there a another way to move the profile from on PC to a new one.
Regards
Otto
