E.28.2. Migration to Version 9.6.4.1

A dump/restore using pg_dumpall, or use of pg_upgrade, is required for those wishing to migrate data from any previous major release.

A dump/restore is required for those running Postgres Pro Enterprise 9.6.3.2, because catalog number format has been changed for better Postgres Pro Enterprise identification.

Dump/restore is necessary when migrating from PostgreSQL, Postgres Pro Standard, or Postgres Pro Enterprise edition.

For upgrades from previous releases of Postgres Pro Enterprise, Postgres Pro Standard, or PostgreSQL 9.6.x, some catalog changes should be applied.

If you use binary packages, and your database is in the default location, this upgrade should be performed automatically. If you've created your database in a non-default location, running initdb manually, you should run the pgpro_upgrade script provided in this distribution.

Before running the script, you should stop the postgres service. The script should be run on behalf of the user owning the database (typically postgres), and the PGDATA environment variable should be set to the directory where the database resides.

When upgrading from versions 9.6.2.1 or lower, you have to rebuild GiST indexes built over columns of the intarray type.
