Upgrading with TPA - If you installed using TPA, you can use its automated upgrade feature to upgrade to the latest minor versions.
Upgrading manually - If you manually installed and configured your PGD cluster, you will find the details and procedures needed to move a cluster between versions, both minor and major, in this section.
Upgrade Paths - This page covers available supported upgrade paths.
Compatibility changes - If you are upgrading from PGD 3.x or 4.x to PGD 5.x or later, this page covers the compatibility changes between versions.
