Upgrading

Upgrading PGD

EDB Postgres Distributed is a flexible platform. This means that your upgrade path depends largely on how you installed PGD.

• ** 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.

• ** Supported PGD 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.
