Ok ... so I set up the new box exactly the way the old one was set-up, I even had the set-up wizard set-up an initial database so it would already create the services and everything needed. All I want to do is swap the datafiles, admin (init.ora) files and files in the /ora90/ database folder. So I logged in as sysdba, shutdown the pre-installed database (same sid as my old one) and replaced files mentioned above with original files where they should go. Then I proceeded to do the following ...

1. startup nomount
2. set dbid ... HERE'S WHERE I'M STUCK, WHERE CAN I FIND MY OLD DBID FROM MY OLD DATABASE? I have all my files but I obviously can't query just the files!

Then I'm going to simply ...

3) alter database mount;
4) restore database;
5) recover database noredo;
6) alter database open resetlogs;

Hopefully, that should do it. I tried doing this proceedure without doing the set dbid and I get stuck trying to do the last step since I'm really unable to do any recovery. Any suggestions? I don't care about losing some data, I just want to get the database up and running. All I have is the cold backup files from the old system.
