Users who purchase a lower-tier ticket can upgrade later to a higher-tier option by paying the difference.
Use case example:
Ticket A = Half-day conference at £60
Ticket B = Full-day conference at £99
User purchases Ticket A, then decides later that they want Ticket B, and only pays £39 extra.
They will need a way to verify their original purchase/ticket ownership. UX flow should make it obvious they can upgrade.
