If you are upgrading from a version older than 3.2:
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.

running the installation script with the upgrade(
Download the latest version of TigerGraph to your system.
Extract the tarball.
Run the installation script under the Linux user created during installation with the upgrade flag (
-U) that was extracted from the tarball:
$ ./install.sh -U
