Provides a guided workflow for your Upgrade

Single source of truth for upgrade impact(reports)

Agent Upgradability

Target Upgradability

Provides different upgrade approachesPerform 12.1 mass agent deployment with required plug-ins (this is the

agent upgrade)

We don't need any SSH connectivity to deploy the agents from theupgrade console as we use the existing agent communication(10.2.0.5

or 11.1) to transfer the bitsSoftware Management for 12.1 Agent and plug-ins

Runs dynamic pre-upgrade repository checks

Before 12.1 agents are activated administrators can run readiness checks
