Jump to another Movable Type; very easy with version 5.12!
Transition to Movable Type 5.0x was a little burdensome to do this and that. Today's transition was just on the fly. What I have done was melting Movable Type tar ball under cgi directory. Then, initial logon triggered upgrade process resulting in successful migration gracefully. That's all!
This is the first post published from Movable Type 5.12 to see if it works.
