Version 8.6 represents a major milestone in the Sentinel RMS product line, as it introduced support for several new license types and features. A key point to note is that licenses using the older LM 7 format are not supported on version 8.6. If your organization still relies on LM 7 licenses, you must maintain a separate server running an older version of the license manager, as two different versions cannot coexist on the same machine.
