Moving 2009 customer AX DB to TEST Environment and use our license keys

I am searching an HowTo to do the following:

I want to import the AX LiveSystem from our customer in our Test-Environment, but we want to use our license keys.

So we do the following:

- import DB in our server

- add aos_service

- patch the SID from admin in userInfo 

update userinfo set SID='S-1-5-21-111111111-1111-11111111-111',

Networkdomain = 'developer',

networkalias = 'administrator'

where id = 'admin'

- add the other user from the domain and add it to the admin group

- start AOS and login with the admin-user

- import licensefile

- AOT sync()

After this we will get the message "insufficent access wrights" and the tables will be deleted....

Whats wrong?

Can anybody help and tell me how's the right way...

ciao
