Symptom
On FMC deployment transcript, you can see that deployment fails due to internal errors.
Doing a pigtail deploy, you can see the following error message just before the deployment fails:
Failed to get version upgrade information for device: Key: NGFW_UPGRADE is missing in map file.,com.cisco.nm.vms.provision.provmgr.PlatformBladeJob
Conditions
Issue may be seen after upgrading or while doing an RMA for a cluster member and adding said member while it has a Major version lower than the current Cluster's major version.
