How to Assess Your Cloud Migration Readiness Before You Start
The decision to migrate to the cloud is straightforward. The execution is not. Firms that begin the migration process without a clear picture of their current state almost always encounter the same set of problems: unexpected dependencies between systems, data in formats that are not portable, applications that require on-premise infrastructure, and connectivity limitations that prevent cloud-based tools from performing adequately. Each of these is manageable when discovered early. Each becomes expensive when discovered mid-migration.
A readiness assessment is the work that happens before the migration work begins. Its purpose is to give the firm a complete, accurate picture of what it is working with — so that the migration can be planned in the right sequence, with the right resources, without the surprises that derail most large infrastructure projects.
The Infrastructure Inventory
The first component of a readiness assessment is a complete inventory of every system the firm depends on. This means every application that stores or processes data, not just the obvious ones. Project management platforms, design software, accounting systems, time tracking tools, email infrastructure, file storage (local servers, NAS devices, shared drives), and any custom or legacy systems that have accumulated over time.
For each system, the assessment needs to determine several things. First, cloud compatibility: does the vendor offer a cloud-hosted version, or does the application require local installation? If a cloud version exists, does it have feature parity with the local version? Some applications have cloud offerings that are substantially less capable than their desktop counterparts, which affects the migration plan.
Second, data portability: can the data in the system be exported in a usable format? Some legacy applications store data in proprietary formats that are not easily moved to new environments. Discovering this before migration begins allows time to address it. Discovering it mid-migration, when a deadline is pressing, is a different experience.
Third, integration dependencies: does the system connect to other systems in ways that need to be preserved in the cloud environment? Applications that exchange data with other tools need those connections evaluated carefully. Moving one system to the cloud may break an integration that another system depends on.
The Connectivity Assessment
Cloud infrastructure performs in direct proportion to the quality of the connection between the firm and the cloud. Before committing to a cloud-dependent workflow, the firm needs an honest evaluation of its current connectivity — not the theoretical maximum speed of its internet plan, but the actual throughput available to users during peak hours, and the reliability of the connection over time.
Most business broadband connections perform noticeably worse during the business day than during off-hours, because the bandwidth is shared with other customers in the area. The peak-hour performance is the relevant figure for a cloud workflow, not the headline plan speed. If the assessment finds that current connectivity is insufficient for the intended cloud workload, the connectivity needs to be addressed before or alongside the migration, not after.
The Migration Sequence
The output of a readiness assessment that is most immediately useful is a recommended migration sequence: which systems to move first, which to move later, and which to leave on-premise for now.
The sequencing should move the simplest, most self-contained systems first. These provide early wins, build organizational familiarity with cloud infrastructure, and generate lessons that improve the execution of more complex migrations later. Systems with complex integrations, large data volumes, or uncertain compatibility should be scheduled later, when the team has more experience and more options for addressing complications.
Some systems may not be good candidates for migration in the near term. Legacy applications with no cloud version, specialized tools with poor data portability, or systems that perform adequately on-premise and have no clear cloud benefit can reasonably be excluded from the initial migration scope. A good readiness assessment is honest about what should move now, what should move later, and what should stay where it is.
