The only changes you may have to make would be
1) the path to perl on the new server.
2) change the url within the .cfg file (i.e. $db_dir_url)
3) In some cases the new server may encrypt the passwords differently so that may cause problems with the password file. I've not had this problem moving to different servers, but it's possible.
If so, the FAQ provides a solution under the section
Admin/Passwords in a thread called:
"Password file corrupted after server change"
