Checking the Current Configuration and Candidate Software Compatibility

When you upgrade or downgrade Junos OS, we recommend that you include the validate option with the request system software add command to check that the candidate software is compatible with the current configuration. By default, when you add a package with a different release number, the validation check is done automatically. For more information about the request system software add command, see the Junos OS System Basics and Services Command Reference .

Note: On an ACX Series router, you must ensure that the primary and backup partitions are synchronized after an upgrade by issuing the request system snapshot command.
