NOS Upgrade Paths

You can upgrade a network operating system (NOS) from a recommended NOS release in a previous Apstra release to a recommended NOS release in a newer Apstra release. In the same Apstra release, you can upgrade between NOS releases. See the sections below for supported paths. Upgrading to an unqualified version does not cause an error' If you upgrade to an unqualified version, be sure to perform due diligence.

For information about other upgrade paths that may be available, or to request support for a specific upgrade path, contact Juniper Support.
