Pre-Migration Checklist for Moving to the Cloud | Sequoia Technology Group
A cloud migration that goes off without a hitch, and one that turns into a scramble, usually comes down to what happened before the actual move. Companies in Sacramento that pair reliable 24/7 IT services with a clear plan for cloud services tend to spot trouble while there is still time to fix it. Companies that rush past that step often hit the same snags at go live, right when pressure is highest and choices are limited.
This checklist walks through the areas that matter most for Sacramento businesses preparing to shift to the cloud.
▌Take a Complete Inventory of Your Current Environment
Before anything moves, you need to know exactly what you have. That means documenting every server, workstation, application, and data store currently in use. This sounds straightforward, but most businesses we work with across Sacramento and the surrounding communities find something during this process they did not know was there.
The inventory should capture hardware ages, operating system versions, application names and versions, and who in the organization uses each system. Pay particular attention to anything that was set up years ago and has simply kept running. Legacy file servers, aging database instances, and applications nobody can quite remember installing are the things that cause the most trouble mid-migration.
▌Map Your Application Dependencies
One of the most common reasons cloud migrations run into trouble is moving a system before the team understood what else it was connected to. Applications share databases, authenticate against common services, read from network drives, and send data to each other through connections that are not always visible on the surface. Move one piece without accounting for the others and you can break processes that were working fine.
Dependency mapping means tracing those connections for each application: what it connects to, what connects to it, and what would break if it went offline for a few hours. This map becomes your sequencing guide during migration, telling you what has to move in what order. For businesses in Roseville or Rocklin running multiple line-of-business applications, this step frequently reveals dependencies that nobody had formally documented.
▌Classify Your Data and Understand What Is Regulated
Not all data carries the same weight, and that matters during migration. A Sacramento healthcare provider moving patient records has to treat that data differently than a construction company moving project files. Correct classification before migration determines which cloud environment the data belongs in, what security controls need to be in place before it arrives, and what documentation needs to exist afterward.
California businesses subject to the California Consumer Privacy Act or the California Privacy Rights Act need to know exactly what personal data they hold and where it lives. Healthcare clients need to confirm that any cloud environment receiving protected health information meets the requirements of HIPAA, the Health Insurance Portability and Accountability Act, before the data moves. Our cybersecurity team helps clients work through data classification before migration begins so the right controls are in place from the start rather than retrofitted after the fact.
▌Assess Your Network Readiness
Cloud environments depend on fast, reliable internet connectivity. A business that has been running primarily on local servers may not have a network built for the bandwidth demands that come with cloud-dependent operations. If the connection at a Folsom or El Dorado Hills office cannot handle the load, users will feel it immediately after go-live.
The network assessment before migration should cover internet service type and speed, current bandwidth utilization during peak hours, Wi-Fi coverage and access point capacity, and firewall rules that may need updating to allow cloud traffic properly. Our network management team runs this assessment as part of migration planning, because finding network limitations after migration is far more disruptive than finding them before.
▌Decide What Gets Left Behind
Not everything in a current environment needs to follow the business to the cloud. Some applications may be end-of-life and better replaced than migrated. Some data may be archivable rather than actively transferred. Some hardware may be keeping a legacy process alive that the business would be better off retiring entirely.
The pre-migration review is the right time to make those decisions deliberately rather than defaulting to migrating everything. Businesses that take the time to clean house before migration end up with a cloud environment that is easier to manage and costs less to run month over month. That clean slate is worth more than most businesses expect once they are settled into the new environment.
▌Establish a Pre-Migration Backup State
Migration is a point of elevated risk for data loss. Systems are in transition, processes are being reconfigured, and mistakes happen. Before the first workload moves, every piece of business-critical data should have a verified, tested backup stored separately from the systems being migrated.
This is not the same as the regular backup schedule. It is a deliberate, point-in-time copy taken specifically to protect against migration errors. If a file or database does not transfer cleanly, a clean copy needs to exist to restore from. Our business continuity team sets up these pre-migration backup states as a standard part of the process and verifies them before migration work begins. Going into a migration without that verified safety net is a risk that is not worth taking.
▌Build a Risk Register Before Go-Live
Every migration has risks. The goal is not to eliminate them but to name them, estimate their likelihood, and have a response ready for each one. A risk register documents what could go wrong during the project and defines the plan if any of those things materialize.
For Sacramento healthcare or legal businesses, compliance-related risks belong at the top. For businesses with remote or field locations in the Central Valley, connectivity risks deserve specific attention. For any business running older custom applications, compatibility is the thing most worth stress-testing before the migration window opens.
Our cloud services team builds a risk register into every migration plan because the businesses that recover fastest from problems are the ones that already had a plan for them.
