Upgrade and new phone

[Bjorntd]

What the exact process of swapping phones and upgrading to my new phone?

I’ve been with republic wireless awhile. I have a Motorola g7 plus and I’m upgrading to a Motorola 5g phone.  

do I use the new sim?  How do I swap my stuff over to the new phone?

If the new SIM is already activated just move it to the new phone. My Motorola phone gave me the option to transfer all apps and files over from the old phone, I don't remember how it did it since that was 4 or 5 months ago.
