Hello Karjac,
I'm sorry to see you're experiencing a 500 internal server error. When the files were transferred over, the files were still not quite setup correctly. I had the Tier2c techs review it and they fixed what may be causing the issue. Please check this again - in this case it was a matter of file permissions. Here's an article that explains this issue:
Causes for the 500 Internal Server Error
