Yes, though which paid plan you subscribe your stores to is dependent on your use case and intentions with Replay.
If you only intend to make a one-time copy, you'll need to subscribe any and all stores being copied to/from to our Pay As You Go Plan.
If you intend to make more than one copy or set up a continuous, ongoing copy, you'll need to subscribe any and all stores being copied to/from to our Unlimited plan.
*Please Note: Stores on one plan will not be able to be associated and copy to/from stores on the other plan. Only PAYG stores will be able to be associated with each other, and copied to/from. The same applies to stores on the Unlimited plan.
