This question about Upgrading from TWiki to Foswiki: Answered
Is it possible to upgrade from twiki 4.3 to Foswiki?
I noticed in the documentation Foswiki supports upgrading from TWiki 4.2.X but it does not mention TWiki 4.3. Has anyone tried to upgrade from 4.3?

Upgrading from 4.3 should be just as easy. Despite the version numbers, not a lot changed between TWiki 4.2 and 4.3. The complete release notes are listed here: http://twiki.org/cgi-bin/view/Codev/DownloadTWiki#TWiki_4_3_Release_highlights
If you have any problems upgrading then feel free to ask here and someone should be able to help you.
