Migrated the websites to RHEL 5. I simply took a backup, installed RHEL 5

and

restored the apps. Bar some config changes in httpd.conf (from apache 2.0 to 2.2), no other modification were done.

As per my knowledge if you migrate to PHP5 from PHP 4 then you need to do changes in php.ini also.

Unfotunately I dont remember exact changes but I had done this 3 months back for one of our PHP-Mysql application. I remember even some PHP4 functions dont work in PHP5. So need to convert those also.
