No, lifetime Premium subscribers will not be converted to a Roblox Plus subscription. Premium subscribers will continue to stay subscribed to Premium.
Premium and Plus are two different subscriptions and the choice is all yours on which you’d like to subscribe to (you can also keep Premium and stack on Plus). All Premium members will receive a free 1-month trial to Plus on launch day (April 30, 2026) so you can check it out.
I’m happy to share that an active Premium membership will count towards eligibility. Plus will not be needed in addition. However, Premium will not be sold to new subscribers starting April 30 - the day Plus launches. If you cancel your Premium account after April 30, you will not be able to resubscribe, and you will need a Plus membership instead.
There are no current plans for this. Games that aren’t available on the platform today would require the original creator to complete the content maturity questionnaire and receive a content maturity rating before they could be made accessible again.
