Define and document backup, restore, and rollback procedures, then verify their implementation before go-live. • Phase 2 — Go-Live and Operation: Support the go-live at the pilot sites and perform the necessary technical checks for startup. Monitor the operation of the environments, analyze alerts and logs, diagnose incidents, and implement corrective actions in coordination with the relevant teams. Test the restore process, verify the results, and update the procedures as needed. Contribute to the stabilization of the solution by learning from encountered incidents and the corrections implemented. • Coordination and Handover: Plan technical interventions with the development and integration teams; specify deployment prerequisites and report any difficulties that could compromise go-live. Maintain up-to-date documentation for configurations, deployments, and operating procedures. Contribute to knowledge transfer to the IT department's technical contacts by presenting the monitoring, diagnostic, backup, restore, and rollback methods.
