How to upgrade to a new micro SD card?
I'm quoting someone who gave the correct answer as a comment
I had already done this since I was trying to figure it out on my own as well
But they worded it better than I could have

If it's removeable storage, it is literally just remove the old card,
insert the new card and format it as removeable, then using a PC copy
the contents of the old card to the new card and insert it into the
phone and you're done
