Records needed for this question
Transition plan, tenant contracts and migration milestones.
How to investigate
Separate planned parallel running from unexplained duplication and assign a completion owner.
An illustrative review decision
During a merger, both tenants may remain necessary until migration acceptance and retention checks finish. Assign owners to those exit conditions rather than treating the entire overlap as immediately realizable savings.
What can lead to the wrong conclusion?
Overlapping charges can be necessary until data and access migrations are accepted.
The result to retain
A transition-cost schedule with decision checkpoints.
Apply the review in context
Technology Spend currently provides an evidence-first demo workspace with synthetic demonstration records. Production sources, tenant integrations and external actions remain disabled until explicitly connected and validated. Keep identified, reviewed, approved, implemented and confirmed savings distinct. Capability overlap is a review signal, not an automatic removal recommendation. Production evidence must remain separate from synthetic/demo records.
