I just ported 2 numbers from a Verizon Wireless family plan. Neither numbers were the account owner. The moment I transferred them, (which was less than 3 mins fyi, almost instant), they disappeared from my Verizon Wireless family plan.
I did some reading - you do not want to port over the Owner's account because if you do, Verizon will close the plan and the lines connected to it may be cancelled - from what I read. So do all the family member lines first, then the owner's line last.
All our phones had e-sim, so we allowed the Visible app to set up a new e-sim, activate service, then started the number transfer (on Verizon Wireless, you have to unlock the number, create a transfer pin) - and within minutes you'll be up and running (remove the old Verizon e-sim once the transfer happens). I've found rebooting the phone helps too.
But yeah, Verizon Wireless considers porting a disconnected - service termination action. I wouldn't do the owner first - do account owner last.
Good luck ๐
