Why Post-Migration Remediation Projects Fail 90% of the Time
Moving data is Logistics.
Refining data is Intelligence.
Six months after a traditional "lift and shift" migration, leadership realizes Copilot is unreliable, search is broken, and compliance is at risk. IT is tasked with "cleaning up the data."
This is where reality collides with hope.
Post-migration remediation fails because:
-
The Graph has already learned: Changing a document's metadata today doesn't erase the fact that 500 users accessed it under the old, wrong permissions. Those users may have bookmarked it, forwarded it, or discussed it in Teams channels. The Graph has recorded all of that activity and built a relationship map based on flawed assumptions.
-
User behavior has calcified: Users have adapted workarounds. They bypass search and use direct links. They've learned not to trust Copilot. They rely on email attachments instead of SharePoint sources of truth. Changing the underlying data doesn't change learned behavior.
-
Breaking changes are unacceptable: Rationalizing permissions might require breaking thousands of user bookmarks and shared links. Renaming files for clarity breaks every embedded reference. Deleting ROT content triggers user complaints ("I might need that someday!"). IT is paralyzed by political resistance.
-
API limitations and complexity: Fixing metadata at scale requires custom PowerShell scripts, Graph API calls, and manual validation. Large enterprises have millions of files. Scripting errors can corrupt permissions or delete content. The risk is too high, so projects are abandoned.
-
No budget or executive sponsorship: The migration project had budget and urgency. "Data cleanup" is seen as IT housekeeping—low priority, no funding, no executive pressure. The project dies in a backlog.
⚠️ The 10x Cost Multiplier
Industry research consistently shows that remediating data after migration costs 10x more than addressing it in-flight. Why? Because in-flight, the data is already in motion—there's budget, urgency, and executive sponsorship. Post-migration, you're asking for a second project to fix a "completed" initiative. The political and technical barriers are insurmountable for most organizations
