Start with the migration path and workload inventory
Exchange and hybrid mail
Mailbox inventory, public-folder strategy, coexistence requirements, certificates, connectors and mail flow.
Microsoft 365 tenant changes
Source and target tenants, identity mapping, domains and the mail or file workloads included in a consolidation.
Files and collaboration
Named OneDrive or SharePoint data, permissions, migration waves and business access checks.
Other source environments
Identify the source platform and the required workloads so supported methods, access and tooling can be assessed before a commitment.
Hybrid Exchange needs a mail-flow plan
A hybrid project must account for the Exchange environment and the cloud tenant together. The portfolio includes hybrid configuration, certificate and connector validation, mailbox batch moves, public-folder strategy, Autodiscover, DNS and mail-flow cutover. Any Exchange retirement follows the agreed validation and decommission plan.
Agree the checks that make a cutover acceptable
- Discover. List users, mailboxes, public folders, shared files, identities, domains and dependencies. Record what remains outside the project.
- Prepare. Confirm licenses, approved access, destination configuration, mapping and the supported workload methods.
- Pilot. Choose a pilot group, record mail and access validation, identify exceptions and agree the cutover and fallback criteria.
- Cut over. Sequence the approved identity, domain, mail and file changes within the agreed window, with named decision owners.
- Validate and hand over. Complete the scoped mail-flow and workload checks, record exceptions, agree acceptance and provide the named post-migration hypercare.
Keep the quote and ongoing support separate
The project quote identifies source and target workloads, data scope, tooling, licenses, preparation, cutover and acceptance work. Ongoing tenant administration is agreed separately. Timing depends on the environment, access, pilot findings and business change windows.
Questions buyers ask
Can you plan public folders and hybrid coexistence?
The portfolio includes public-folder strategy, hybrid coexistence planning, Exchange configuration, certificates and connectors. The project scope must identify the folder and mailbox requirements, selected methods and acceptance checks.
How do you check a migration before cutover?
A pilot and agreed validation checks are part of the project plan. Name the mail-flow, identity, domain and file-access results required, the exceptions that must be resolved and who authorizes cutover.
How long will our Microsoft 365 migration take?
A schedule follows discovery of users, data, identities, source access, licenses, dependencies and business windows. The written project plan defines milestones and acceptance rather than one duration for every environment.
Is support after the move included?
The proposal names the hypercare period and tasks, acceptance process and any ongoing administration service. These responsibilities should be agreed alongside the migration work.
