Upgrading to Cisco Unified CCX 7.0(1)
for Cisco Unified CSS Users

This chapter describes how to upgrade from CRS 4.5(x) or 5.0(x) to Cisco Unified
CCX 7.0(1) for Cisco Unified Communications Software Subscription (Cisco
Unified CSS) users.

Cisco Unified CSS License Upgrade

A Cisco Unified CSS license, which is currently known as Essential Operate
Software and Cisco Unified Communications Software Subscription (Cisco
Unified CSS), allows you to pre-purchase major software version upgrades.

If you are a Cisco Unified CSS user, and you are upgrading to a valid upgrade
path, data migration is supported. If the upgrade path is not valid, you are only
entitled to a software/seat upgrade, which does not involve the migration of
historical and configuration data from the old version to the new version. The
features that were licensed in the previous version will continue to work in the
new version provided those features are not made obsolete in the new version.

For the Cisco Unified CSS upgrade to work, you must upload the Cisco Unified
CSS upgrade license (a single license file that indicates the old version and the
new version of the upgrade license), along with the existing licenses (for the old
version).
