    The details on what upgrade paths are supported are found in the release notes for the final target version, in your case 21.4, organized by platform, in your case EX.


    Here you can see there is support for 3 major version jump, the first number in Junos version.  So you can go directly from 18.1 to 21.4 on the ex4600.
