One of our users posted a meta question on main, so one of our mods migrated it to our meta site.
The interesting thing is that the user (owning an account on both meta and main by default), deleted his questions from meta. The result was the migration being cancelled, and the post ending up back on main (although closed with an "Off-topic" reason).
As immediate reaction, I migrated again and instructed the user to not delete his question, but that seems rather undesirable. Is it possible to exclude self-deletions from the migration rejection triggers?
I've tested it (by migrating a test question to Stack Overflow and deleting it from there) and it works even cross-site, as long as OP has an account on both sites. Question on Stack Overflow (10k+), Question on Anime & Manga (2k+)
