Migration Roadmap
Our proven 4-phase process for a smooth open-source migration.
Migration Roadmap
Every successful migration follows a structured process. Our 4-phase model minimises risk and maximises success.
Phase 1: Analysis & Planning (Week 1–2)
Current State Analysis
We fully assess your existing IT landscape:
- All Microsoft products and versions in use
- Number of users and devices
- Critical business processes and dependencies
- Special requirements (industry software, integrations)
- Current data protection level and GDPR risks
Migration Plan
Based on the analysis, we create:
- Prioritised migration sequence
- Timeline with milestones
- Risk assessment and mitigation measures
- Training plan for employees
- Budget and ROI overview
Phase 2: Pilot Project (Week 3–4)
Selecting a Test Group
We first migrate a small group (5–10 people):
- Ideally tech-savvy employees
- Representative of typical work processes
- From different departments where possible
Pilot Operation
During the pilot:
- Both systems run in parallel
- Feedback is collected systematically
- Issues are resolved immediately
- Training materials are refined
Phase 3: Migration (Week 4–10)
Step-by-Step Rollout
Migration takes place department by department:
- Infrastructure migration (servers, network)
- Data migration (files, emails, calendars)
- Client rollout (workstations, laptops, mobile devices)
- Application migration (specialist tools, integrations)
Parallel Operation
During migration, both systems run in parallel until all employees have been switched over. No data loss, no production downtime.
Phase 4: Training & Stabilisation (Week 8–12)
Employee Training
- Group workshops (2–4 hours per team)
- Individual sessions for power users
- Written guides and video tutorials
- Point of contact for questions
Stabilisation Phase
After migration:
- Weekly check-ins for 4 weeks
- Immediate response to any issues
- Fine-tuning of configurations
- Handover to your internal IT contact
