Upgrading from Movable Type 2.6x and earlier
Users upgrading from Movable Type 2.6 and earlier wishing to upgrade to Movable Type 4.0 are requested to first upgrade to Movable Type 3.35 and then upgrade to Movable Type 4.0.
We are making this recommendation based soley on the fact that Six Apart did not extensively test the upgrade process from MT 2.6 directly to 4.0. While technically it should work, and there are no known issues with upgrading in this fashion, we can only offer upgrade support to users upgrading from 3.x.
Previous versions of Movable Type can be downloaded from our archives.
