  • Optimization: Identify opportunities for optimization and improvement in the new environment.

10. Documentation and Knowledge Transfer:

  • Documentation Update: Update documentation for the new environment.
  • Knowledge Transfer: Ensure knowledge transfer between the migration team and the operational team.

11. Contingency Plan:

  • Rollback Procedure: Have a well-defined rollback procedure in case issues arise during or after migration.
  • Emergency Support: Establish emergency support channels for immediate assistance in case of critical issues.

Building a comprehensive IaaS exit plan involves careful planning, testing, and communication to ensure a successful transition with minimal disruptions to business operations. Regularly review and update the exit plan to adapt to changes in the infrastructure or business requirements.
