Changing Database Strings (Migration)

[d0cpaul]

I recently moved to a new dedicated server from a shared hosting account on GoDaddy. They migrated my database files and etc. Now I update all my config.php settings such as:

database name
server name
user name
password

But now I am getting a database error. I spoke with a tech over at GoDaddy and he said:
"This issue appears to be caused by incorrect connection strings."

Me: So how would I got about fixing these strings?

Tech: Unfortunately, I would not know the locations of all of the connection strings. However you can verify that it is not an issue with PHP or MySQL as my test script connects without issue.

What connection strings do I need to change to make this migration complete?
