Pixel 2 XL How do I get back to setup (for transfer of data etc)

I took delivery of my Pixel 2 XL yesterday (love it) but during the setup when it was connected to my old phone (galaxy S6) my old phone encountered the 'black screen of death and I had to cancel the setup at that point. I have a google account so no problems with gmail, google photos calendar etc.... just phone logs, messages etc that need to be transferred.
Any help would be greatly appreciated.
