MoinMoin is a “fairly mature” software package.

• Our installed release is the latest release, 1.9.11.
  • The FreeBSD port is marked deprecated due to its reliance on the obsoletepython 2.7.
• The next release has been announced to be 2.0. See the RoadMap.
  • However, note that no release date is scheduled.
  • There will be a possibly nontrivial effort to convert our contents to the new codebase. MoinMoin's own development documentation is unclear on this.

If, in the future, we decided to migrate the content to another wiki package, the cost would be quite high. Apparently the markup that MoinMoin uses is … interesting.

Migration to MediaWiki could be done, but it sounds painful.

• MediaWiki's MoinMoin to MediaWiki article contains the following scary note: There are a number of hacky scripts for this. They are all defective in various ways - anyone who does this job does it precisely once.
• The w3.org Moinmoin to Mediawiki migration Manual does not sound cheerful, either.
