Overview
This document walks through the process of upgrading an ICE Server installation from versions 3.5.X to version3.6.5.
Upgrade considerations:

Initial RallyPoints are created and registered automatically.

When a RallyPoint or static reflector is deleted via ICE Desktop, whether intentionally or on accident, they will reappear after ~30 seconds.

If the ICE Server IP address is updated, then refer to the
Update RallyPoint(s) when the ICE Server IP address changes section of the
ICE Desktop User Guide for additional steps to perform.

ICE 3.6 introduces Groups. All Servers will be placed in a Group. After the upgrade, you may modify the Groups as needed with the exception of Group and Server names, which may only be applied during creation of the Group or Server.
