Are you using Azure migration tools that abstract away the infrastructure layer without understanding what lies underneath?

Before I touched a cloud-migration tool, I created virtual servers using ISO images and managed WSUS patches across 1,600 Windows Servers. Windows Server versions 2003 to 2016. VMware vSphere Infrastructure Management without the convenience of cloud abstraction layers. This path into migration engineering is becoming increasingly rare, and I think it shows.

The Azure Migrate Tool has a lot of documentation and is capable. The engineers who make the most of it will be those who know what they’re doing, and not just how to configure a tool that does all the lifting.

To migrate 100 or more physical and virtual VMware server workloads to Azure, you must know how they were configured on premises. Storage type and IOPS requirement. Network dependency mapping between servers which were communicating on a network local and now have to communicate over an Azure virtual network topology. Differences in application behavior between bare metal or VMware-hosted executions and Azure VMs. These are not questions about tool configuration. These are infrastructure knowledge questions that can cause performance issues after migration if the answer is incorrect.

PowerShell scripting from managing 1,600 servers and scripting SCCM agents deployments and SCEP installation across enterprise infrastructure translates directly to the PowerShell scripting required by M365 Migration Specialist roles for managing directory objects and mailboxes at scale. The scripting discipline developed in an on-premises setting where automation was essential for survival is also the discipline that scales when working with cloud migration.

WSUS patch sequence across 1,600 servers created the planning discipline required for migration runbook design. Sequencing, rollback triggering, and responsible party assignment are not concepts that you encounter for the very first time when writing your first migration runbook. These are the same decisions that you made in a different context.

Engineers who can troubleshoot an infrastructure-layer migration failure rather than a tool-layer migration are harder to come by than job postings would suggest.

What infrastructure knowledge do you apply to your cloud migration that the tooling can’t substitute?
