Migration Playbook: Moving into Colocation with Zero Downtime

Migrating infrastructure to colocation is a complex undertaking that requires careful planning to avoid service disruptions. This comprehensive migration playbook walks you through every phase, from initial assessment and provider selection to physical migration and cutover. We cover application dependency mapping, risk assessment, creating detailed runbooks, testing procedures, and rollback plans. Learn how to implement parallel running environments, use DNS and load balancer techniques for seamless cutovers, and validate functionality before decommissioning old infrastructure. The guide includes checklists for pre-migration tasks, day-of-migration coordination, and post-migration validation. Whether you're moving from on-premises, another colocation facility, or partially from cloud, this playbook helps ensure a successful transition.
