Introduction

The procedures for upgrading Universal Controller differ from the procedures for applying maintenance to Universal Controller.

For Universal Controller 7.3.x:

• Upgrading refers to the increase of a currently installed 5.2.x version of the Controller on a machine to a 7.3.x version of the Controller (for example, upgrading Controller 5.2.0.2 to Controller 7.3.0.0).
• Applying maintenance refers to the increase of a currently installed 6.1.x or later release of the Controller on a machine to a 7.3.x release of the Controller (for example, applying maintenance to Controller 6.2.0.1 to increase it to version 7.3.0.0).
