Migrating from FreeBSD servers array to RHEL 5

[okasion]

Hi everyone, this is my first post to the maillist.

Well, basically I'm asking for opinions to get help on our migration of
operative systems.
Our company its a hosting that gives webhosting and basic fast mailservices
besides other small things. We have very personal and flexible relationship
with our customers and their needs.

We have been using FreeBSD since year 2000, and besides "the normal
problems" (ports upgrade, UFS - NFS maintenance, RPC daemons working weird,
etc,), it has proven to be an incredible operative system that will make
very old hardware reliable to make money.

We are migrating now because we want to enter the virtualization world,
offer housing, Java support, and have "real" support from Red Hat so we can
take vacations once in a year and turn off our Nextel and forget about
alarms. Also, people who knows Linux/Red Hat are MUCH common than FreeBSD
guys, so that would help in the future when hiring more personal.
I know much of the technical services we want to offer can be deployed on
FreeBSD, but we also know these services are much easy and stable to install
and use on RHEL.

I am the main sysadmin and grew up with Red Hat since I was sixteen, (I'm 23
now) so I used Red Hat for a long time until I liked more Slackware and then
Gentoo to use at home at least; I really have faith in Red Hat for servers.

We are used to code everything on our own (C, PHP, PYTHON, Bash, old ASP,
etc.) so it will be a little weird to migrate to Red Hat at first (rpm
packages against FreeBSD ports its the main reason I think), but that's the
point, use our time to offer new services rather than maintain the current
ones with custom bugfixes.

Any opinion will be appreciated. Thanks in advance guys.
