We have Plesk 5 on our server, and we've been frustrated with the inability to upgrade pieces of the server software.

For instance, my server guy tells me that we can't upgrade to MySQL 4 or the latest version of PHP because Plesk is hard-wired for the versions we have now.

Has this changed? Can I upgrade to different versions of software, or even different software, than what Plesk comes with? For instance, we like a certain DNS package. Can we use this with Plesk, or are we stuck with what Plesk comes with?
