You could clone the database to the server you need them on.
Check out this tip from Don Burleson:

I have two servers with 2 databases that connect to the same datafiles (the datafiles are on shared drivers). one is primar and the other is secondar, theyre reflect each other changes.
The problem is that I need to remove one of this servers and replace it with an other, I have created an identic database in the other server,as in the server I have to remove, now I need to connect it with the shared datafiles.
WHAT CAN I DO!!!!!
