Upgrading F5 Big-IP from version 9.1.x to 9.3.1 - Local Install

1. Download the image (.im) and accompanying md5 file from the F5 support site.

2. SCP to your Big-IP and transfer the image and md5 file to the directory /shared/tmp

3. Connect to the Console port of your Big-IP. This ensures during reboot you do not loose connectivity to the CLI of the Big-IP.

4. Extract the .im file and run installation script. Apply the following command:
im local-install-9.3.1.37.1.im

5. The system then prompts you for some installation options to be selected.
