What is Cross-Platform Document Migration?

The difficulty is reconciliation rather than transfer. Each system identifies documents, users and permissions in its own terms, so a straight copy produces an estate where the same person holds different rights depending on which source a document came from. Metadata is worse — fields that appear equivalent frequently are not, and mapping them by name produces a taxonomy that is internally inconsistent in ways nobody detects for months. Harmonization in Centralpoint performs that reconciliation during ingestion rather than as a pre-migration project: identity is resolved across sources, one governance dictionary applies regardless of origin, and taxonomy assignment places every record in a structure the business recognizes. Content from four systems arrives under one consistent classification rather than four translated ones.
