Today I spent a couple of minutes (yeah, minutes!) to upgrade my personal blog (in Japanese) to MT 3.2, from MT 2.51 with Japanese patch. It was pretty straightforward, except I had to take a dump of mysql and converted it into utf-8 from euc-jp, which I thought makes a trouble somehow.
The automatic upgrade process is pretty slick and did a nice job to upgrade everything without any problem. All I had to do was manually copying the necessary plugin (most of all are unnecessary now thanks to default SpamLookup plugin) and modifying the hardcoded charset strings in templates.
Kudos and Thanks to the MT team!
