When a regulated investment organization asked us to replicate their Alfresco environment in SharePoint exactly as-is, we pushed back. Not because we couldn't — but because we knew a simple copy job would create more problems than it solved.
Instead, we ran a structured content analysis. What we found: out of ~100 metadata fields, only 15 were actually in use. Permissions were configured in ways that would have breached SharePoint's own limits. And folder structures carried years of undocumented logic.
So we redesigned rather than replicated. The result: a leaner, faster, audit-ready SharePoint environment — with permissions that work, metadata that means something, and end users who actually notice the difference.
