Knowledge held by one person
Capture operating knowledge in diagrams, procedures, access requirements, recovery steps, and assigned responsibilities.
LEGACY SYSTEM MODERNIZATION / 3PSUNDERSTAND THE OLD.
UNDERSTAND THE OLD.
BUILD WHAT COMES NEXT.
The legacy platform still runs important work. 3PS maps its applications, infrastructure, data handoffs, and operating knowledge, then connects stabilization to a phased modernization plan with validation and rollback.
500+ customers served.
Backed by 100+ professionals and technical resources across our delivery network.
Establish the current state before the cutover.
- 01
Inventory the system
Document servers, databases, jobs, applications, licenses, service accounts, vendors, users, and interfaces.
- 02
Map the handoffs
Identify what sends, receives, stores, or transforms data, including timing dependencies and the effect of late or missing information.
- 03
Validate the recovery options
Check backups, restore paths, snapshots, installation media, access requirements, and vendor support.
- 04
Stabilize the operating boundary
Scope security, access, monitoring, and change-control improvements around the constraints of the existing production system.
- 05
Support the transition
Add reporting, alerts, file checks, integration guards, or exception handling where they help sustain the workflow during modernization.
- 06
Sequence the replacement
Define phased migrations, test evidence, rollback criteria, owners, and leadership decisions before the platform changes.
Make the dependencies visible.
Unsupported components
Assess operating systems, databases, runtimes, licensing, security, hardware, and vendor support before choosing a replacement path.
Brittle interfaces
Map files, APIs, HL7, EDI, reports, scheduled jobs, and the places a missed handoff can fail without an alert.
An incomplete migration plan
Establish the source environment, business workflow, validation, dependencies, and rollback before changing the platform.
THE WORK IN MOTION
Keep the workflow connected through the change.
The system record and the route forward.
Dependency map
Applications, databases, servers, jobs, users, vendors, files, APIs, and reports.
Risk register
Unsupported components, access issues, backup gaps, single points of failure, and relevant compliance concerns.
Recovery evidence
Backup and restore checks, installation media, access requirements, vendor dependencies, and a documented recovery sequence.
Stabilization plan
Prioritized changes, expected effects, owners, validation, and rollback for work on the current platform.
Modernization roadmap
A phased replacement or integration plan with dependencies, testing, decision points, and operating responsibility.
The agreement defines the permitted production work, change approval, validation, and rollback requirements.
Keep progress visible between migration stages.
Technical and vendor oversight
Review legacy risks, vendor dependencies, recovery readiness, documentation, and planned changes within the engagement.
Workflow safeguards
Maintain relevant reports, alerts, file checks, integration guards, and exception paths as source and replacement systems evolve.
Recovery readiness
Keep restore order, access, backup evidence, and owners aligned while the business still depends on the existing platform.
Examples of continuing work. The agreement defines covered systems, deliverables, resources, working hours, reporting, and response commitments. Hardware, software, dedicated resources, and projects are included only when stated; Critical Response is separately priced.
LET’S DEFINE
THE NEXT MOVE.
Bring the objective, the environment, and what needs to change. We will connect the right disciplines around a defined engagement.
