For those keeping track at home, this is the link I primarily used:
Switch from an iPhone to a Pixel phone - Pixel Phone Help
I did turn off imessage and facetime (never used it) as in the instructions before I did anything else.
In my case I left the iphone active and fired up the new pixel. After a few initial setup screens it asked about another device, so I went through the steps, I had a C to Lightning cable and my real concern was that the iPhone was so old (6S with IOS 15x) that it might not work or worse, would damage something. But it mostly went flawlessly. It even moved over (well, reinstalled) my apps, which was a great benefit. All my text history is there, as well as my contacts. I was also able to reuse my physical sim, after I got everything copied over I put the pixel in airplane mode, swapped the nano sim into the pixel and waited about a half-minute and turned off airplane mode.
The only thing that didn't work well was all of the info I had in the iPhone "Notes" app, which came over to the "Keep" app in the android. While they are kind of there, they are just a mess, mostly completely worthless. But I can live with that.
I also have a steep learning curve, having been off the android platform for way too long.
