Supported PGD upgrade paths v5
Upgrading within version 5
You can upgrade from any version 5.x release to a later 5.x release.
Upgrading from version 4 to version 5
Upgrades from PGD 4 to PGD 5 are supported from version 4.3.0. For older versions, upgrade to 4.3.0 before upgrading to 5. See Upgrading within 4 for more information. Generally, we recommend you upgrade to the latest version 4 release, before upgrading to the latest version 5 release. After upgrading to 4.3.0 or later, the following upgrade paths are possible.
| From version | To version |
|---|---|
| 4.3.0 | 5.0.0 or later |
| 4.3.1 | 5.1.0 or later |
| 4.3.2 | Upgrade to 5.3 (once it is released) |
Upgrading from version 3.7 to version 5
At this time, TPA has only enabled upgrades from PGD 3.7 to 4 and PGD 4 to 5. Customers moving from 3.7 to 5 and desiring automation would need to use this two-step upgrade path and will potentially have their proxy architecture changed multiple times from HA Proxy to HARP and finally to PGD Proxy.
Significant development has been done to make upgrading directly from 3.7 to 5 possible and easier. We've expanded the database versions supported with PGD 5 and enabled the upgradeability of the BDR extension across multiple PGD versions. Previously, we only supported upgrades from the previous major version. Often, a database upgrade was also required because only one database major version was supported by both PGD versions.
Development is currently ongoing to provide a direct upgrade path from 3.7 to 5 using TPA by Q4. In the interim, customers may reach out to EDB Professional Services or Support for assistance and guidance.
