A 1-license upgrade to upgrade a Sync'Em Contacts version 1.xx license to a Sync'Em Contacts Plus version 1.xx license.

Upgrades are delivered via a licensing code called an Upgrade ID.

Each of the license upgrades within a Sync'Em Contacts 1.xx to Sync'Em Contacts Plus 1.xx Upgrade ID can be used to upgrade a license in a Sync'Em Contacts 1.xx License ID. After being upgraded, the licenses in the Sync'Em Contacts 1.xx License ID will function as Sync'Em Contacts Plus 1.xx licenses.

Note: because all the licenses within a given License ID must be the same kind of licenses, all the licenses within a given License ID must be upgraded at the same time.
