Migration Roadmap 

A structured five phase plan to guide your organisation through the transition away from Project Online before its 2026 retirement.

Your Project Online Migration in 5 Phases

Follow this roadmap to assess your current Project Online setup, evaluate Planner, the PMO Accelerator and ISV solutions, run pilot projects and complete your migration in controlled 
waves before 2026.

1.

Kickoff 
(1 to 3 weeks)

  • Review current Project Online usage and custom fields.
  • Inventory active projects, integrations and reporting dependencies.
  • Confirm the migration sponsor and core project team.
  • Define scope, success criteria and timelines.

2.

Assess and Decide 
(4 to 8 weeks)

  • Analyse project complexity and classify them into Light, Medium or Complex.
  • Map each project to Planner, the PMO Accelerator or an ISV solution.
  • Identify governance, compliance and reporting needs.
  • Document required configurations for each tool.

3.

Pilot and Validate 
(8 to 12 weeks)

  • Select representative pilot projects across all complexity tiers.
  • Test Planner, the PMO Accelerator and an ISV tool using real project data.
  • Validate usability, reporting gaps and scheduling limitations.
  • Refine configurations based on pilot feedback.

4.

Migrate by Wave 
(3 to 9 months)

  • Migrate Light projects first to minimise risk.
  • Follow with Medium and Complex projects once processes stabilise.
  • Validate dashboards, dependencies and data quality after each wave.
  • Provide user readiness training for each wave.
