Upgrading LM-X and version compatibility
To upgrade the server at the end user site:
- Uninstall and remove the old LM-X license server.
- Install the new license server obtained from your software vendor.
Important: When upgrading LM-X to a newer version, note the following compatibility considerations:
Existing deployed client applications and existing license files will continue to work with the new version. However, new license files cannot be used by older applications.
If you distribute floating licenses, your end users must also upgrade their LM-X license server, because the old license server cannot support new licenses (i.e., we cannot provide "future" compatibility). In most cases, borrowed licenses will also continue to work. However, borrowed licenses rely on using Secure Store, so if Secure Store is changed (which is rare), borrowed licenses will not be backward compatible.
- If you are using any external shared libraries—for example, for .NET, Java, etc.—you must also deploy these new versions with your software.
- You can install multiple versions of LM-X, but do not mix files between different distributions, as this can cause problems such as compilation or runtime errors. The only file that can safely be shared between platforms is the security configuration file, security_config.lmx.
Note: To upgrade the server at the end user site:
- Uninstall and remove the old LM-X license server.
- Install the new license server obtained from your software vendor.
Be sure to read the release notes for all new LM-X releases to learn of any issues that may affect version compatibility.
