See task T280461 and the discussion at https://translatewiki.net/wiki/Thread:User_talk:Aandeginini/Ojibwe_translations . I also spoke to an external expert, who confirmed that this is a good move.
The procedure for doing this should probably be the same as in task T174601. If I understand correctly, however, since ciw translations were never exported from translatewiki to Git, it will be easier because it just needs page moving and no dealing with JSON files.
