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.
Pre-upgrade Guidelines
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:
Upgrade Guidelines
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:
Post-upgrade Guidelines
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:
