What should I do if I asked a question on wrong meta (MSO instead of MSE) post-split; and by the time I realized that it was the wrong meta - meaning the question is about all sites and not SO only - it was already commented on and fully answered on MSO?
Should I just leave it on MSO?
Ask a duplicate question on MSE?
Ask a duplicate question on MSE and link to MSO one?
Flag for moderators to migrate to MSE? (assuming that's a valid migration path).
The usual rules about MSO/MSE split doesn't apply here since all the other split-related migration issues that I saw pertained to MSE=>MSO migrations.
