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