02/05/2022 - Solution that worked for me!!! (Android Pixel 3XL to iPhones 13 Pro Max). I was able to move all old text messages with Wondershare MobileTrans - Phone Transfer. It cost me $20 and the program was a little finicky. I had to disconnect and reconnect the phones a few times to get both fully loaded in the program. You will also have to change connections on the android by going to "Developer Mode". To be clear I am not a developer. I just followed online directions. MoblileTrans was pretty efficient in giving prompts to make the move. It took about 5 minutes of set up and another 5 minutes to move 15,500 texts. As for Apple.... They suck. Like many others I was on the phone with support 5+ times for hours. My phones would connect and count down to anywhere from 1 hour to 1 minute and stop. After about 30 minutes of no movement "Transfer Failed" popped up. On my final call to Apple support I was told that Apple is aware of the issue and no workaround is available for "Move to iOS" at this time. I am very disappointed given the "It Just Works" image that they project.
