Possible to merge two iMessage conversations?

[imkc_long]

My wife got a new phone number (long story -- had to be done). We've been messaging each other with the new phone number, but it's keeping the old iMessage conversations separated. Call me sentimental, but I'd like to keep the old conversations, which includes messaging from the time of our wedding a couple months back.

Is there any way to combine the two iMessage threads into one on my iPhone? Or is this a hopeless venture?

Can't do it. iOS12 has a feature that should do the merging automatically, but it doesn't work, and no one knows/writes about it anyway.

hi
unfortunately, no. there does not appear to be any way of joining multiple conversations.
going forward, to be sure, the absolute best way of ensuring that no matter what SIM or mobile number anyone has in their phone, if people set iMessages to always be sending from their apple ID, to other people's apple ID (not mobile fon numbers) there will always only be 1 threaded conversation between these two people, no matter initiated or received on any device. and is easy to backup and sync.
