Chicken or the Egg?

Invt

Greetings,
I have a new Pixel phone arriving in a few days and plan on installing Graphene OS. My question is whether I should first migrate my existing Android phone to the new Pixel then install Graphene or if I should first setup the phone, transfer the phone number to the Pixel, then change to Graphene. Sorry if this a stupid question!
Thank you!

Invt grapheneOS wipes all data from the device during install, install it, verify it works, then move data.

Invt If you're moving an eSIM, moving it before installing GrapheneOS can be easier in some circumstances.

1st, make your existing phone closer to gos-like setup (foss apps, etc), then move
