Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
I have a parent who was already connected in the Pack but, when his daughter was registered in my Troop, he wasn’t connected to his original account, they created a new one.
Pack, connected ID

New Troop ID, can be deleted but has additional info to include (i.e. address):
Member ID

He needs to use 14435662. The other one is missing his date of birth and is missing the parent / children relationships. I set 14435662 as primary yesterday.
