What must be understood before moving content?
Inventory the source content, metadata, access rules and downstream integrations. Record exceptions early and give each unresolved decision an owner. Document counts are one reconciliation measure, not a complete definition of success.
When is federation useful?
Federation can provide a common access layer while repositories remain separate. Evaluate the ongoing operating costs, permission mapping and query behavior, and define an exit condition when federation is intended as a temporary bridge.
What makes a cutover ready?
Agree the checks for content retrieval, permissions and dependent workflows. Rehearse the intended sequence and rollback approach using representative data. Confirm retention and disposition decisions with the content owners before excluding material.
