Upgrades and Migrations
This section explains how to upgrade Unified IC software with engineering specials, minor
releases, and maintenance releases as they become available and to migrate an older version of
Unified IC Release 8.0(1) or 8.0(2) to Unified IC Release 8.0(3) running on a Virtual Machine.
An upgrade typically happens inplace and requires no hardware change whereas a migration
involves change in hardware. To continue with Upgrade, see About Upgrades (page 35). To
continue with migration, skip the initial tasks in this section and start with About Migrations
(page 41).
To upgrade, you must obtain the upgrade executuable file (page 36) and then apply it using the
Cisco Unified OS Administration application (page 37).
