Guidelines for Upgrading Cisco APIC and OSP
The OpenStack plug-in is released with Cisco Application Policy Infrastructure Controller APIC releases, and therefore uses the same semantic version as Cisco APIC. For example, the 5.1(1) plug-in is provided with the Cisco APIC 5.1(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.
