Infrastructure with savings plan to be decommissioned

Hi there, We are currently running 2 websites on separate infrastructure and plan to decommission the older site after we have moved the domain across to the newer one.

We have a savings plan for the older website that still has a couple of years to run but nothing for the newer one. So I wanted to know what would happen to the plan when the older website was decommissioned. Would we face any penalties for not seeing out the term or could the savings plan be transferred to the newer website?
