Upgrading IWAN App
This chapter provides information about upgrading IWAN Application:
IWAN application requires an additional network upgrade step when the APIC-EM upgrade process is complete. After the APIC-EM upgrade process is complete—the “reset-grapevine” and the 30-minute wait for inventory resynchronization—the IWAN main landing page will look as shown in the following image.
You need not upgrade IWAN unless you need a new IWAN application workflow or update the network to leverage the new IWAN controller functionality. You can either perform the upgrade immediately or schedule to perform the upgrade in the future, at a convenient time or when the network is down.
To upgrade, click the text Network upgrade is required to use the IWAN App in the main landing page. The Upgrade Summary window appears.
The upgrade information is sent to all affected sites in the network and will show on the site status screen as a provision in-progress for those sites. Once the upgrade is complete, normal site status will prevail.
After performing the upgrade clear the browser cache. Cisco IWAN App is now ready to accept further input.
