A cloud migration assessment that ends in a decision, not a slide deck.

Most migration programs fail in the planning gap: the inventory exists somewhere, but nobody trusts it enough to commit. A cloud migration assessment closes that gap by turning read-only discovery into a scoped, costed plan with a pilot boundary you can actually sign.

One-sentence versionA good assessment answers four questions — what exists, what depends on what, what is ready to move, and what is the smallest safe first step.
Outputs

What a usable assessment produces.

The deliverable is not a document — it is a decision-ready evidence base. These are the outputs that separate a real assessment from a discovery export.

  • Inventory — the authoritative list of objects, mailboxes, sites, and workloads in scope, from read-only discovery
  • Dependency map — which items must move together, and which block others
  • Readiness findings — grouped by action: ready, review, remediate, defer
  • Risk register — the topology, permission, and timing risks with owners
  • Pilot boundary — the smallest representative scope with explicit acceptance criteria and a rollback owner
Method

From discovery to a defensible plan.

The sequence matters more than the tooling. Each stage feeds the next, and skipping one produces a plan nobody should trust.

DiscoverRead-only inventory of source and target across directories, tenants, and workloads.
AnalyzeSurface collisions, unsupported items, and dependencies; group by readiness.
ScopeDefine the pilot boundary and the waves that follow it.
ValidateDry-run the pilot scope to confirm mappings and detectable conflicts.
DecideCommit only when the pilot evidence supports it.
Readiness

How BridgeAD runs the assessment.

BridgeAD discovery and assessment are read-only: they inventory and analyze without modifying source or target systems. Findings become an execution scope only after you approve them.

  • Read-only discovery across AD, Entra ID, Exchange, SharePoint, OneDrive, and Teams
  • Readiness findings categorized ready, review, remediation, or deferred — never a single opaque score
  • Duplicate and collision detection before any scope is frozen
  • A pilot boundary with acceptance criteria and rollback ownership, agreed before execution
  • Exportable findings you can act on whether or not you continue with BridgeAD
FAQ

Common questions.

What does a cloud migration assessment produce?

A usable assessment produces an inventory of what exists, a dependency map, readiness findings grouped by action (ready, review, remediate, defer), a risk register, and a scoped pilot boundary with acceptance criteria — not a slide deck.

How long does a cloud migration assessment take?

It depends on estate size and access. A focused assessment of a representative scope — a forest pair or a workload subset — typically completes in days once read access is granted, and is the fastest reliable input to a migration decision.

Does the assessment change anything in our environment?

No. BridgeAD discovery and assessment are read-only. They inventory and analyze without modifying source or target systems; execution begins only after the scope is approved and a pilot boundary is set.

Make the migration decision from evidence.

Bring one representative scope — a forest pair, a tenant, or a workload subset. You get findings, a dependency map, and a pilot boundary you can defend.
