Guidelines for Upgrading Cisco APIC and OSP
The OpenStack plug-in is released with Cisco Application Policy Infrastructure ControllerAPIC releases, and therefore uses the same semantic version as Cisco APIC. For example, the 4.2(1) plug-in is provided with the Cisco APIC 4.2(1) release. Generally, the OpenStack plug-in releases are tested against the matching Cisco APIC release, as well as the previous Long Term Support (LTS) Cisco APIC release. However, a given plug-in release may be compatible with additional Cisco APIC releases. See the Cisco ACI Virtualization Compatibility Matrix to verify that the version of the plug-in used is compatible with the version of Cisco APIC.
See the Cisco ACI Virtualization Compatibility Matrix for information about compatible Cisco APIC and Red Hat OSP releases.
You need to first upgrade the Cisco Application Centric Infrastructure (ACI) plug-in.
For more information about the compatibility of the plug-in with various OpenStack versions, see the Cisco ACI Virtualization Compatibility Matrix at:
The Cisco ACI fabric can be upgraded following the information on Cisco Application Policy Infrastructure Controller (APIC) Management, Installation, Upgrade, and Downgrade Guide at:
Optionally, you can upgrade the Cisco ACI fabric without upgrading the plug-in, as long as the Cisco ACI plug-in and Cisco ACI fabric release combination is supported. For more information, see the Cisco ACI Virtualization Compatibility Matrix at:
After you upgrade the Cisco ACI fabric, you can optionally upgrade the OpenStack ACI packages to a version which is equal or lower than the ACI fabric code you have upgraded to. You should also refer to the OpenStack ACI Plugin Release Notes for specific information:
