This is the second Beta release of the gpupgrade utility for Greenplum Database. The gpupgrade utility upgrades a Greenplum Database system from an earlier Greenplum Database version to a newer major version.
The gpupgrade utility can be used to upgrade a Greenplum Database 5 system to a Greenplum Database 6 system.
The source Greenplum Database 5 system must be at the latest 5.x Greenplum Database release. For pre-upgrade prerequisites and source cluster preparation, see gpupgrade Pre-upgrade Phase.
The target Greenplum Database 6 system must be upgraded to the latest version of Greenplum Database 6.x, downloaded from VMware Tanzu Network.
gpupgrade does not support upgrading Greenplum Database 4.3.x systems.
This release supports a configuration file for gpupgrade initialize. The configuration file replaces the command line options used in the first Beta release. For usage and options, see Running gpupgrade Initialize.
This release supports gpupgrade revert, which restores the source cluster to its original state. You may use revert after gpupgrade initialize and/or after gpupgrade execute. For further details, see Reverting gpupgrade Actions.
This release provides migration scripts that target some of the pg_upgrade checks that are executed during gpupgrade initialize and gpupgrade execute. For information on the script types and their usage guidelines, see Using the Migration Scripts.
