Upgrading an Existing Installation

This page describes the steps to upgrade an existing installation of TigerGraph to TigerGraph 3.2.

This page lists all the versions you can upgrade from through self-service. If you are trying to upgrade a production system to 3.2 from a different version than those listed on this page, please contact TigerGraph Support first.

Upgrading from v3.1.5/v3.1.6

TigerGraph 3.2.1 includes a critical patch to 3.2.0. Please upgrade to 3.2.1 instead of 3.2.0.

Please only upgrade to 3.2 from 3.1.5 or 3.1.6. If you are upgrading from another version, please upgrade to 3.1.6 first, and then upgrade from 3.1.6 to 3.3. For instructions on how to upgrade to 3.1.5/3.1.6 versions, see Advisory for upgrading to 3.1.5+.

Before you begin

• Use GBAR to perform a backup and restore on your existing installation. This step is necessary because TigerGraph 3.2 made major changes to the Graph Storage Engine and a restore is needed to remove certain files that would make the upgrade operation fail.

• After restoring the backup, ensure that there are no vertex inserts or deletions before starting the upgrade.

Procedure

1. Download the 3.2.1 version of TigerGraph to your system.

2. Extract the tarball.

3. Run the install script under the Linux user created during installation with the upgrade flag (-U) that was extracted from the tarball:

$ ./install.sh -U
