If I change my domain name, can you re-issue my license key?

Question:
If I change my domain name, can you re-issue my license key for the new domain name?
Answer:
This depends on your license type. There are two common techniques used to offer licensing for a software product like Centova Cast, and each has drawbacks.Option #1 is to use "re-issuable" license keys which can be re-licensed to other domains. This approach requires that the product must periodically "call home" over the Internet to contact the vendor's licensing servers and verify that the product is still licensed for the domain it's running on. The drawback to this approach, however, is that if the vendor's licensing servers go down, or the vendor goes out of business, or the client tries to firewall outbound traffic, the product will be unable to validate its license and the software will cease to operate. Option #2 is to use permanent keys which are cryptographically strong, and do not need to "phone home" to be revalidated. The drawback to this approach is that the key needs to be permanently assigned to a particular domain name, and cannot be changed due to the nature of the technology used to generate them. For versions of Centova Cast prior to v2.0, only option #2 was offered for Centova Cast. As of Centova Cast v2.0, re-issuable licenses are available for purchase by popular demand, and have become our default license type. If you have ordered a re-issuable license, please see this article for instructions for changing your licensed domain name. If you have not ordered a re-issuable license, we are unable to re-issue your license key for a different domain name. Regrettably, we cannot make exceptions under any circumstances. |
