If the CMS is memory hungry then check the log files for: PHP Fatal error: Allowed memory size of bytes exhausted (tried to allocate bytes) And update the PHP ini file accordingly. I suspect that you could get a usable system for 5 users in 256MB of RAM / 1 CPU 1.7 is fine or lower) and what ever image size that covers your install + growth. If a CMS is being used for 5 people then it must be a wiki / KB or something similar? You could just dump the db and write a PHP navigation tool and be done with it.

Marty, ofcourse, but, it's a custom CMS it's no longer used in production, only used as legacy for 5 users only, and, requires login to access (and, hopefully login doesn't have security vunerability...), and, is the only application on this host I've tried putting it on newer system (Centos 5 and 6), it print php code to browser (or, won't display page), some of it is might do with code page -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Here is how I would do it (which is probably not the best way ever): - if there is live data already in the system create backup to two location and check if you really have the data in both - see how you get on with the installer - try to install the CentOS4 php under CentOS 5 or 6 - run CentOS 4 environment in chroot / virtual machine Good luck! -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] downgrading from Centos 5 to 4 ?
I have a machine running Centos 5, I'd like to downgrade to Centos 4 in order to run an older PHP CMS that require 'older' PHP, (it seems easier to run older system that upgrade the CMS) do I simply boot from Centos 4 media and run install? # /sbin/fdisk /dev/hda The number of cylinders for this disk is set to 3649.
