Re-assigning older magic bands

[NYCgrrl]

Hi everyone.
I have 10 older magic bands - not the 1st gen, the ones with the removable puck.
I am wondering if there is a way from home I can deactivate two of them that are on my profile and re-assign them to my two kids? All the families profiles are listed on my account.
I'm wondering if I can do it myself or if I have to do it at the resort when we arrive?

Just a heads up somewhat on topic: you don’t have to buy a Magic Band. Gave the kids their old ones (sounds like the same model you have) and got a free pass card for myself. I have much better things to do with my money
