I get to be a beta tester for MT3! I won't be converting over right away though. I thought I'd set up a duplicate database and test the beta using that so that I can iron out what changes I'll need to make to my templates. So for a little while, I'll be running parallel weblogs.
Upgrading the MT database was pretty simple. Had everything up and running in a matter of a few minutes, although I haven't rebuilt an of my weblogs yet. I've recently run into few issues with plugins that I'm trying to sort out. After I get those resolved, I'll start messing around with MT3.
Looking forward to this.
