When to move SIM card when updating iPhones?

My wife is about to upgrade from an old iPhone to a new one. We plan to move all her stuff from the old to the new, either by backing up the old (which we will do in any case, of course) and then restoring to the new, or by using the Quick Start method ( https://support.apple.com/en-us/HT210216 ) to move all her stuff.
In either situation, we are unclear whether to do all the transferring and then move the SIM card from old to new, or to move the SIM card to the new iPhone before we even begin the transfers.

I don’t think it matters, since the SIM card on iPhones is mostly used for the actual phone network info, not personal information. I would move the SIM card to the new iPhone before beginning.

Thanks, Chas,
I will do it that way then and hope for the best. 2 days and counting!
