Next came compatibility testing. In the sandbox he installed the manager and deployed the legacy client to a simulated endpoint. He watched logs for installer errors, compatibility warnings, and attempted connections to external telemetry servers. The manager’s configuration referenced an external update repository the factory couldn’t reach; Raj modified the configuration to point only to internal repositories. He documented the changes and prepared a rollback plan.
Raj started by mapping stakeholders.
