EL Migration Project
The EL Migration Project is a 1 year project which will involve upgrading our infrastructure, which is entirely Debian, to Enterprise Linux. VTLUUG has had issues with Debian, including terrible defaults, upgrading packages overwrites configuration file without warning or means to intervene, inconsistency among packages, and init script issues. EL is a enterprise ready linux distribution that actually has a major company, RedHat, backing it. It doesn't have these problems.
How will it work
Upgrading your entire infrastructure to a new distribution is not an easy task. We are currently in the planning phase. In a few weeks we will be releasing a downtime schedule for our upgrades. We hope to have our entire infrastructure unbroken in a year.
Progress as of 2016-03-21
We gave up. Only Cyberdelia and Razor are running on CentOS; all other services currently run Debian 8, or, in the case of Milton, Debian 6.

it *may* behove us to move to CentOS/Ubuntu to use FreeIPA. It is a nice all-in-one Kerberos solution, which will be more maintainable (one would hope) than Blade.
