iMessage in iCloud - Time Machine Backup
I was trying to free up space on my iPad and accidentally hit delete iMessage history after 1 year in iMessage- thinking it would just affect the iPad. Since I had iMessage in iCloud enabled it deleted all my iMessage history after 1 year from all of my devices (iPhone, Mac, iPad) as well as in iCloud (~10 years of iMessage history (25GB)). I didn't have it in an iCloud backup since I was using iMessage in iCloud.
I thought I had permanently lost it but remembered I have been doing Time Machine backups on my Mac which is synced with iCloud iMessages.
My question is: if I restore the iMessage database (including all conversations, attachments, etc) from that iMessage Time Machine backup on my Mac then re-enable iMessages in iCloud will it re-sync all of the deleted messages from iCloud and return them to all the devices?
