After [#4646] we should move sf.net/p/allura/wiki content to allura-vm.apache.org/p/allura/wiki We can do this with the
wiki-copy.py script, which is currently in SF's private repo, but should be moved over to Allura proper. It'll copy main page content, but not attachments, history or comments I don't think. We'll have to manually deal with those.
After complete, a link tool can be set up at sf.net/p/allura/wiki to redirect to apache. IIRC, it should handle specific pages correctly too.
