Has anyone found any issues with upgrading from PHP4 to PHP5? Is everything backwards compatible?

Overall, most stuff is backward compatible. However, if you have E_STRICT on, you will get warnings for many classes designed for PHP 4. Reference usage changed around completely, so you will need to update the code for that.
