There are certain circumstances under which you might need to
        regenerate, renew, or rehost Adaptive Server licenses.
            Licenses must be upgraded to the
latest versions when:
- 
                        Your support contract is renewed. Updated
licenses enable you to use the newest versions of the products that
become available during your support period. 
- 
                        A new product version is added to your entitlement. 
Licenses need to be rehosted when:
- 
                        You
entered incorrect machine information when generating the license. 
- 
                        The host ID of the machine has changed due to a
hardware upgrade. 
- 
                        You transfer products to a new machine. 
You can either upgrade or rehost all licenses that were previously
                generated for a specific host (see Managing License
                    Hosts in the Sybase Software Asset Management (SySAM) 2 Users
                    Guide), or you can modify individual licenses (see Modifying Individual Licenses in the Sybase Software Asset
                    Management (SySAM) 2 Users Guide).
