VMware to Azure Local Migration: The Failure Modes That Begin After the VM Replicates

This article provides a comprehensive field guide for VMware to Azure Local migration, emphasizing that successful replication does not guarantee a successful migration. It details failure modes that occur after VM replication, such as operating system blue-screens, offline data disks, lost static IP addressing, incomplete portal information, disabled guest management, and application transaction failures. The guide covers the entire migration process from source discovery to post-cutover acceptance, including preparation, replication, cutover, networking, troubleshooting, guest management, monitoring, backup, and workload resiliency. It stresses that replication is only a transport milestone and that the migration team must validate storage and network drivers, IP identity, boot generation, secure boot, guest management, Azure portal projection, backup, monitoring, and application testing before completing the migration. The key rule is to not complete migration until all checks pass and a rollback decision has expired.
