Migrate from Self-Managed RabbitMQ to AmazonMQ

Hello team, IHAC who wants to migrate their self-managed RabbitMQ solution to a fully-managed solution. Today, they use plugins MQTT and AMPQ to support these two protocols. I was checking and the only solution who support both protocols is AmazonMQ for ActiveMQ. I would like to know if the customer needs to refactor their application to move from RabbitMQ to ActiveMQ. I saw that there is a PFR to support MQTT with AmazonMQ for RabbitMQ, but it still in Reviewed - On-Roadmap, but not I need to an estimate to become GA.
