Major release version change to 4.0
RHACS includes a major architecture change, moving the Central database to PostgreSQL. This change provides important performance and scale benefits.. We strongly recommend backing up your ACS database prior to upgrading to ACS 4.0. For this reason, RHACS 4.0 is controlled through a new subscription channel. Customers need to explicitly change their subscription channel as part of the provided upgrade instructions. By default, RHACS installation includes the PostgreSQL database. Future plans include the ability to use your own PostgreSQL compliant software. RHACS 4.0 supports this option as a Technology Preview with certain limitations.
