They can be edited, but that may alter their format. Before today's release, editing a previously migrated forum post would just completely strip out its formatting. After today's release, the result of editing an old forum post may be similar. I can't say yet how editing a migrated forum post will look like after future migrations. A lot has chanced in Discussions since the last time we migrated a community's forums into it, so that script will need to be substantially updated - and then we may at least be able to keep some of the old formatting when editing a migrated post.
