The recent change to reject question migrations broke a rather useful workflow when it came to cross-posted questions. When a cross-posted question is found, it's common for one site to keep it and the other to close (to avoid splitting answers):
- Site A migrates the cross-post to site B, which already has it (so now it has two)
- Site B closes the new question as a duplicate of the old one
- Site B deletes the migration stub
Since migrated posts and merged posts (even when deleted) automatically redirect users, this had the effect that users viewing the post on site A were redirected to the cross-posted version on site B. Now that procedure results in the post on Site A being recategorized as "off-topic". Supposedly that doesn't happen if the post was closed as an exact duplicate, so I think it happened when the migrated post was deleted, but I'm not sure
Can we skip reversing a migration if the deleted target post was merged first?
