To upgrade from an earlier version of Xchange to version 2.5 or later, your installation must be licensed for Software Assurance. The upgrade will fail if the Xchange installation is not licensed for Software Assurance.

A serial number is an eight or ten character alpha-numeric code that represents a customer's purchase of Xchange licenses for a single site, i.e. a single installation. For clarity, there is no zero (0) in codes but there can be the letter O.

On the central licensing registration server, one or more licenses are associated with each Serial Number. When a customer uses the Serial Number, these licenses are transferred to their Xchange Server PC.

If a customer rebuilds their Server PC or transfers it to a new PC then they would normally keep their Serial Number but it would need to be "released" so that it can be used again.

A Site Id is a 12 character code that represents the current installation of the Xchange Server at a given site. To license a server, the Serial Number (which represents the purchase) and the Site ID (which represents the server) are used to generate a unique License Unlock Code.

For security purposes, you must make contact with the Xchange Licensing Team in order to complete the re-license process for the Xchange Software. Before re-licensing, you must make a note of the following information:

  • The Serial Number registered to your Xchange Server Software
  • The Site ID of the Xchange Server PC
  • The Release Code given when the Serial Number has been released (there is a button to "Release" the Serial number attached to the Xchange Software on the Telephony page)
  • Which Version of the Xchange Server and Client Software you are currently running
  • The Customer name
  • First line of the address registered to customer

Completing this process will re-validate the original serial number which can then be used for either of the two options below.

  • If the Xchange Server Software requires re-installation, after the PC has been successfully rebuilt, the original Serial Number can be re-entered and the software registered in the usual methods, either Automatically, or Manually.
  • If the Xchange Server Software requires migration to a new server, then the software and original serial number can be installed and entered as normal.
Note: If you wish to migrate the original server settings from the original server please follow the steps described here: click here

Cumulative license are stored on the Serial Number. To perform an upgrade you do not replace the Serial Number, but upgrade it. Upgrades are processed by adding the number of required licenses to the Serial Number.

Then at the customer's site, in the Licensing page of Xchange Server Configuration you can use the "Refresh Licenses" button to transfer the licenses over the web, or the "Add License" button to refresh the licenses using the manual registration method.
