PXF Upgrade and Migration

When you upgrade your LightDB-A Database system, you must perform some additional steps in order to bring your PXF configuration up to date.

There are two possible scenarios:

1. LightDB-A Database 5.x to 6.x upgrade or migration:

   • If you are using the gphdfs external table protocol to access data stored in Hadoop in your LightDB-A Database 5.x installation, you must first migrate your gphdfs external tables to use PXF instead, since LightDB-A Database version 6 removes support for the gphdfs protocol.
   • PXF actions are required if you choose a gpupgrade-based LightDB-A Database 5.x to 6.x upgrade.
   • PXF actions are required if you choose to manually migrate from LightDB-A Database 5.x to 6.x.

2. LightDB-A Database 6.x to 6.newer upgrade: You may be required to perform PXF upgrade actions when you upgrade from a previous LightDB-A Database 6.x version. Note that different steps are outlined based on your PXF installation source: a manually installed rpm or deb package downloaded from Tanzu Network, or the PXF version included with the LightDB-A Database Server installer in versions 6.18.x and older.

If you are upgrading a PXF rpm or deb installation independent of a LightDB-A Database upgrade, refer to the PXF upgrade documentation.
