At X-Formation we make every effort to ensure that existing deployed software will continue to work with future license servers, and older license files can be read by newer servers. However, although we will strive for backward compatibility in all future releases of LM-X, we cannot guarantee maintaining compatibility if doing so might compromise the security of protected applications.

Be sure to read the release notes for all new LM-X releases to learn of any issues that may affect version compatibility.


The following table shows compatibility between LM-X versions, where version 1 is older than version 2:

License Files/ClientsLicense ServersCompatible?
Version 1Version 1Yes
Version 1Version 2Yes
Version 2Version 1No

Note that the license file cannot be newer than the LM-X version; therefore, be sure to generate license files as old as the oldest version of LM-X used to deploy your application.
