With regards to MySQL, be sure to backup your databases. There is no way to restore MySQL 5 databases into MySQL 4.1 (if you choose to go back) so be sure to make backups while you're still on 4.1.

As for PHP, PHP 4.3 is very old. Some of your customers running old scripts that haven't been updated in 4-5 years may experience problems with a migration to PHP 5. You may wish to use both PHP 4 and 5 (with PHP 5 as the default) until you can ween all your customers off PHP 4. PHP 4 has been EOL'd since 8/8/8.
