We need an equivalent to https://www.mediawiki.org/wiki/Phabricator/versus_Bugzilla for RT. Maybe we don't need the Improvements section, but the Timeline, Known Issues, and Data migrated should be there.
I've added "Known Issues" and "Data migrated" to https://www.mediawiki.org/wiki/Phabricator/versus_RT.
"Timeline" was too late now and "Improvements" don't know if someone really cares. :)
Ready to close from my point of view, leaving it to Quim whether more content is wanted.
