Converting Hobby (Legacy) to Hobby account

I’m looking to export one of my databases but I get this message when I mouse over Create Export: "Exports are not available on this legacy plan. Upgrade to a modern plan to unlock this feature.”

My question is - how do I remove the legacy from my hobby plan? I see hobby is still offered, but there is no option to change plans except to higher paid tiers.

Turns out the plan that was legacy was the postgres starter plan. Once I switched the plan to basic-256mb I was able to download. I did not need to adjust my Hobby account itself.
