Planning a Movable Type Upgrade

I’m enjoying my last few moments of liberty before heading into what I’ve mentally been terming “the month of hell”. Sometime in the next month, we’ll be upgrading our install of Movable Type Enterprise to the latest version. That means testing over 100 blogs to see that their template all perform fine, as well as making sure nearly 200 people are training in using the new version.
Eeek.
Oh, and because that all looked too easy, we’re also changing the server architecture while we do it. So, the next few weeks are going to be interesting to say the least. I’m used to blog upgrades being pretty trivial (bar that one time [a WordPress upgrade broke everything](http://www.onemanandhisblog.com/archives/2007/09/wordpress_woes.html)), but doing these things at a corporate publishing scale just changes the playing field. 
I’ve taken the last few days off blogging, to give myself an Easter break and to gather my reserves for the weeks ahead. But now I’m back to it. I’ll try to blog my way through the process, but posting here might be even more erratic than normal, depending on how easy – or how hard – it all turns out to be.
