  • Verify the minimum content release version.
  • Identify the preferred release.
    See the Palo Alto Networks Support Software Release Guidance and End-of-Life Summary for more information. Additionally, review the known and addressed issues, upgrade and downgrade considerations, and limitations for your target PAN-OS release to understand how a PAN-OS upgrade may impact you.
  • Determine the upgrade path.

  • Review the upgrade/downgrade considerations for all releases in your upgrade path.

      and test the

      to check that the DNS can resolve the address.
      If it doesn’t resolve, change the DNS to
      8.8.8.8
      (you need to use a public DNS server rather than your own DNS server) and ping again.
      If this doesn’t resolve, change the update server to

      and
      Commit
