I had an iPhone, and used iMessages with iCloud enabled. Then I switched to an Android for a while, which contains new messages. I've now switched back to an iPhone, and am trying to migrate these new text messages into the iMessages app on my new iPhone.
My first try was to restore my new iPhone from my last iCloud backup, and use the dr.fone tool to import these messages, but they did not appear.
Second try was to reset the iPhone (so not logged into my iCloud), and copy the messages to it with the same tool. This worked fine until I logged into iCloud to upload these messages and they vanished.
Does anyone have a solution to this, that will end up with my existing Messages history intact, with any new messages being migrated across and synced properly into Messages in iCloud?
