I was finally able get the the posts from my old MT blog (at www.rocasa.us/~jame) imported here to Blogger. The way I ended up doing it was to import them to WordPress; then export from there, convert that to Blogger format and then import it here.
I have them published now but noticed a couple of issues for at least some of the posts. One issue is that at least some links either did not make it through the migration at all or they are not correct, so will need to go through them at update at least that information. Another issue is with Catagories and Tags, which were/are separate things in at least Movable Type, where it looks like only the Catagories made it through the migration.
