By feature I'm referring to the configuration hierarchy in your device configuration. You search these major terms in feature explorer and this will show whether this can be configured on which devices.
Yes, the process is tedious to be sure on this.
As a general rule if you have the config loaded and working on a vMX it is going to work on the MX240 and up series. But the only way to be positive is to confirm it in the lab or run all the major feature stanzas through feature explorer and confirm they are permitted.
