<title>Migration to Version &productname; 9.6.5.1</title>

<para>Depending on your current installation, the upgrade procedure will differ.

</para>

<para>To upgrade from a <productname>Postgres Pro Enterprise</productname> version based on

any previous <productname>PostgreSQL</productname> major release, you can perform a dump/restore using

<xref linkend="app-pg-dumpall">, or use the <xref linkend="pgupgrade"> utility.

The first option is safer, while the second is faster and can significantly

speed up the upgrade process for large databases.

</para>

<para>To upgrade from a <productname>Postgres Pro Enterprise</productname> version

based on the same <productname>PostgreSQL</productname> major release,

a dump/restore is not required. Instead of the <literal>pg_upgrade</literal>,

you must use the <literal>pgpro_upgrade</literal> script provided

in this distribution. This script updates metadata information to

handle catalog number format change introduced in

<productname>Postgres Pro Enterprise</productname> 9.6.4.1. If you are upgrading your

<productname>Postgres Pro Enterprise</productname> installation from a binary package, the

<literal>pgpro_upgrade</literal> script is run automatically, or you

are prompted to run it manually.

</para>

<important>

<para>

If you run <literal>pgpro_upgrade</literal> manually,

you must stop postgres service.

The script must be run on behalf of the user owning the database

(typically postgres) and PGDATA environment variable should be

set to the directory where database resides. Running <literal>pgpro_upgrade</literal>

as root will result in an error.

</para>

</important>

<note>

<para>On RPM-based Linux distributions, if you are upgrading from

version 9.6.1.2, make sure to move the data directory from

<filename>pgsql</filename> to the <filename>pgproee</filename>

directory before running the <literal>pgpro_upgrade</literal> script.

</para>

</note>

<para>To migrate from vanilla PostgreSQL 9.6.x or <productname>Postgres Pro</productname>,

perform a dump/restore using <xref linkend="app-pg-dumpall">.
