Existing servers use MySQL 5.0.xx and PHP 4.3.xx... New servers are running MySQL 5.0.xx (also) and PHP 5.1.x...
Thanks Are there any "tweaks" you need to do while migrating? I'm on MySQL 4.X and PHP 4.X and would like to move to MySQL 5.X and PHP 5.0
Nope... I didn't change anything between MySQL 4.x and 5.x, and I don't expect I'll need to do anything for PHP4 to PHP5.
