I have a problem :0 At my place of work we have two wiki systems and I have been charged with finding a way of migrating from a MediaWiki to a redmine wiki -- only problem is they use different markup languages (WikiText vs Textile) and a possible solution (Pandoc) only goes the other way :0 Any suggestions on how to do this would be greatly appreciated!!!
The MediaWiki to Redmine Migration Tool (MRMT) has just been released.
It migrates the whole history with the correct user assigned to each revision.
Besides a basic Pandoc translation it also adds some helpful replacements that will very likely be necessary in any migration of that kind.
