iPad 1 -> new iPad setup questions

Sorry if this is repetitive or basic. This is my first "upgrade" of one device to another vs just buying for the first time.

Before starting, I will completely shut down iPad 1, to not complicate anything.

I expect that setting up this new iPad on Friday will follow the basic procedures of adding a new device: turning on, doing the typical time zone settings, plugging into iTunes on laptop, follow the prompts, etc...... No idea how long this will all take (I am currently backing up to the cloud).

Then I assume after the new iPad has everything the old one had, I do the steps for unlimited data (which there are several threads about, so no need to repeat!).

Finally I turn back on the original iPad 1 and doing the data plan change (sign up as new device with different email address and pick whatever limited plan I need).

Is there anything I left out? Thanks all!
