I am not LEO or a licensed attorney. I have been trying to understand how can I best locate, export and make functional use of the data in my iPhone/icloud. I have been trying to self-teach and learn through errors for 3 months now; but I am out of time and need these “missing” messages like yesterday!

The text conversation (mix of sms and iMessage) is saved to iCloud that is available, but I am missing the original 3 months of this conversation thread that I need to locate. Obstacle 1: It was manually deleted at the time, 3 years ago, but I believe has to be retrievable some how! Obstacle 2: I have switch phones since then. The original phone is accessible if needed to retrieve there - however, my iCloud account that would have held the messages is on the new phone.

I have a personal license for iAmazing which I did complete a full phone encrypted backup to a local location and external ssd as well. I have not found any way to locate messages, text, sms or other message related data. If this isn’t the best /easiest way to do this any recommendations or other suggestions ?
