Can I carry a license in 2 different states

you can have licenses in as many states as you want.

You can maintain as many licenses as you care to pay the renewal fees for.

You would have two licenses.

State certificates do not transfer. For instance, while working in Indiana, I needed an Indiana certificate to administer PPD tests, while working in Ohio, I needed an Ohio IV certificate.

I carry LVN/LPN licenses in 3 different states: California, Texas, and Oklahoma. My California license is delinquent simply because I have not lived there in nearly 4 years and, therefore, do not wish to pay the fees that would keep it active.

Since my initial licensure is from California, I endorsed this license into Texas 3 years ago. I also endorsed into Oklahoma several months ago. My licenses in Texas and Oklahoma are active.
