Easy8: From workarounds to workflows
TL;DR
Microsoft Project Online shuts down on September 30, 2026, making all unmigrated data inaccessible and giving organizations a chance to replace fragmented project management workarounds with a more connected and scalable operating model, such as Easy8.
Process or workaround?
Somewhere between reading Microsoft's announcement and comparing alternatives, a different fear appears. Not that the migration will fail.
That it will reveal your project management processes were never really processes at all... It is basically just workarounds built around the software. And that fear is well-founded.
Why is MS Project is EOL
Let's dive deeper into the story of the project management tool that hasn't met the relevant requirements so far...
On September 30, 2026, Project Online retires. After that date, access to the Project Web App and its data is switched off. If you have not migrated, your projects and historical records are gone.
Why is this happening? According to Microsoft, it is retiring the legacy SharePoint-based architecture to focus on modern work management and AI-powered experiences.
But honestly, for organizations that are not fully Microsoft-centric, this retirement may be less an upgrade path than a signal to evaluate alternatives.
MS Project Online retirement timeline
The key Microsoft Project Online retirement timeline is as follows:
- October 1, 2025: New subscriptions stopped being sold.
- April 1, 2026: Existing customers were blocked from creating new PWA sites.
- September 30, 2026: Final retirement; service shuts down, and data is no longer accessible.
If your organization hasn't started migrating yet, the time to act is now. According to the article, delays increase migration costs by 15–20% per quarter and risk a costly, rushed transition.
The change does not affect Project Desktop (MP/Pro) and Project Server Subscription Edition, both of which remain fully supported.
The end of Project Online changes the conversation
Microsoft offers three paths forward:
- move to Planner Premium,
- migrate to Project Server Subscription Edition
- adopt a third-party project management platform
Planner is Microsoft's strategic direction, but it works best for organizations already operating entirely within Microsoft 365.
For engineering teams spread across GitHub, Jira, Product Lifecycle Management systems, and other specialized tools, it is often not a replacement so much as a different product for a different operating model.

The X-ray moment to your project management
Here is what actually happens when organizations start migrating. They open the export, look at the data, and discover that what they thought was a project management system was mostly one senior PM manually translating reality into fields the tool could understand.
Lack of real-time collaboration
Part of the problem was architectural. The schedule lived in Microsoft Project. The conversations that kept it relevant lived in Microsoft Teams. Bridging the two became a process of its own.
"The spreadsheet project management"
The Gantt chart did not reflect what was happening in GitHub. The resource plan did not match what engineers were actually working on. Status reports were assembled from Slack threads and email on Thursday afternoons then entered into Project Online to give leadership a view already 72 hours stale.
The tool was not tracking the work. It was the artifact produced after the work was already being managed informally by one person, in a file only they could edit.
Why obvious MS Project replacement makes it worse
The standard response is to find a tool with similar features, migrate the data, and rebuild the same workarounds in the new system. This is what most of the industry is selling: feature parity, migration paths, "everything you had, now in our platform."
If you migrate the workarounds, you preserve the dysfunction. You spend six months on a migration and arrive somewhere structurally identical but locked into a new platform for five years.
The organizations that use this moment well ask a harder question first: what does a working PM operating model actually look like for the kind of work we do?
The data fragmentation problem
Engineering progress lives in GitHub or Jira. Timelines in Project Online. Resource capacity in a spreadsheet one person owns. Institutional knowledge in a SharePoint folder nobody opens.
This is not a project management problem. It is a data fragmentation problem. Here is what that stack actually looks like on the ground:
Tooling gaps
- Current tools are fragmented and insufficient for the complexity of aircraft development programs
- Dassault 3DEXPERIENCE manages design data but does not provide adequate project oversight
- Microsoft Planner only supports basic task management — no strategic visibility across programs
Visibility failures
- No unified view across engineering systems, milestones, and dependencies
- Leadership lacks consolidated visibility into progress and risks
- Heavy dependence on spreadsheets creates inefficiency and poor scalability
Operational risk
- Increasing engineering complexity creates operational risk without structured PM processes
- Risk of delays, bottlenecks, and coordination failures across the aircraft development lifecycle
Planner Premium does not fix any of this. It does not reach into your PLM, does not connect to your engineering systems, and does not give leadership the consolidated view they need. Migrating to Planner is not a step forward for organizations like this — it is a lateral move that trades one set of limitations for another.
MS Project Online vs. Easy8
The real question is not which tool replaces MS Project Online, but what a connected operating model looks like where PM actually reflects reality.
The table below breaks down exactly where MS Project Online falls short and where Easy8 is built differently, so you can walk into the replacement conversation with facts.
Methodology support
| Capability | MS Project (Online) | Notes to MS Project (Online) | Easy8 |
|---|---|---|---|
| Waterfall / Gantt |  | Powerful scheduling engine, but painfully rigid and complex. | |
| Agile - Scrum boards |  | Not a built-in methodology. Available as a custom task board view, requires manual sprint setup in the desktop client. | |
| Agile - Kanban boards | | Kanban view exists but is layered onto a Gantt-first data model. Not designed for Kanban-native workflows. | |
| Hybrid (waterfall + agile) |  | Waterfall and sprint-based projects are separate plan types. It cannot be combined in a unified program view. | |
Collaboration
| Capability | MS Project (Online) | Notes to MS Project (Online) | Easy8 |
|---|---|---|---|
| Real-time co-authoring | | Desktop client uses check-in / check-out. One editor at a time, others get read-only until the file is released. | |
| Team member task updates | | Team members can log progress via PWA portal. PM retains master schedule control. | |
Integrations
| Capability | MS Project (Online) | Easy8 |
|---|---|---|
| GitHub / GitLab integration | | |
| Jira / external PM tools | | |
| Works outside Microsoft 365 | | |
Knowledge & Compliance
Capability | MS Project (Online) | Notes to MS Project (Online) | Easy8 |
|---|---|---|---|
| Integrated knowledge base | | Completely absent; requires external tools. | |
| Data sovereignty / on-premises | | On-premises available via Project Server Subscription Edition only. | |
Easy8: From workarounds to workflows
Microsoft Project Online's retirement is not just a migration event. It is an opportunity to rethink how project management actually works across your organization. Simply moving to another tool often preserves the same disconnected processes, spreadsheets, and manual reporting that existed before.
For organizations managing complex programs, the real requirement is a connected platform that links projects, resources, workflows, and business systems in real time.
Easy8 provides that foundation, helping teams replace workarounds with a unified operating model that scales with their business. Try it for free!

Traditional project management was built for a predictable, linear world that no longer exists. Today's problems, such as siloed teams, tool fragmentation, and rapid change, require an ecosystem approach, not project-by-project oversight. WorkOps creates an intelligent, interconnected work environment where automation, AI and humans combine to deliver continuous value. Let's deep dive into the topic.
