NOTE
The first step to upgrade the software to V5R3 is to backup the image of the existing software release. For more
information, see Chapter 1, "Backing up the existing image."

You must clean the browser cache before each upgrade. The browser caches the old Javascript files. If the upgrade
is attempted without cleaning the browser cache, the GUI may fail.
To clean the browser cache:
• Click Tools, point to Internet Options, and then select General.
• Click Delete Files. The Delete Files window opens.
• Select the Delete all offline content checkbox, and then click OK. The browser cache is cleaned.
