The migration orchestration engine that moves thousands of users from legacy PBX to Microsoft Teams Phone — with pre-flight validation, automated rollback, and zero manual configuration errors. Days, not weeks. Guardrails, not hope.
Enterprise PBX-to-Teams migrations fail because they are run from spreadsheets, executed manually, and have no rollback plan. One wrong policy, one missed DID, one failed license assignment — and the phones stop ringing.
Each user requires license assignment, voice routing policy, dial plan, calling policy, DID assignment, and emergency address configuration. Multiply that by 500 users in a migration wave, and every step done by hand is a step that can fail silently.
When a manual migration breaks a user's phone service, the fix is manual too — trace the failure, determine the cause, reverse the change, reconfigure. That can take hours per user while the business is without phone service.
Who moved which user? When? What policies were applied? Was the DID ported correctly? Manual migrations leave no consistent trail. When compliance asks, IT scrambles to reconstruct what happened from emails and spreadsheets.
Every stage of the PBX-to-Teams migration — automated, validated, and logged.
Move hundreds of users in a single orchestrated wave. MigrationsIQ handles license assignment, voice routing policy application, dial plan configuration, calling policy assignment, DID mapping, and emergency address setup — all in a single automated workflow. Define the wave, set the cutover window, and execute. No spreadsheets. No manual steps. No missed users.
Before any user is migrated, MigrationsIQ runs a comprehensive readiness assessment. Is the Teams Phone license available? Is the DID free and portable? Is the dial plan compatible? Is the emergency address configured? Are all dependent policies in place? Pre-flight catches failures before they happen — not after the phones stop ringing.
If any step in the migration fails — license assignment error, policy conflict, DID porting issue — MigrationsIQ automatically rolls the affected user back to their pre-migration state. No manual intervention. No detective work. No extended downtime. The user's phone service is restored to its previous configuration while IT investigates and resolves the root cause.
MigrationsIQ manages the end-to-end lifecycle of phone number porting — from the legacy PBX carrier to Microsoft Teams Phone. DID inventory tracking, port order management, number assignment during migration, and validation that every user receives the correct number. Number management persists beyond migration for ongoing DID lifecycle operations.
Every migration action is logged with timestamp, actor, user affected, action taken, and result (success or rollback). The audit trail covers license assignments, policy applications, DID porting events, rollback triggers, and configuration changes. When compliance or an auditor asks "who moved this user, when, and what was applied," the answer is a query — not a reconstruction from email threads.
Every migration follows the same orchestrated pipeline — plan, validate, migrate, verify. Each step must pass before the next begins.
Define the migration wave: which users, which site, which cutover window. MigrationsIQ imports user lists, maps current PBX configurations, identifies DID assignments, and builds the migration plan. The plan includes license requirements, policy mappings, and DID porting dependencies — all computed, not manually assembled.
Pre-flight checks run against every user in the wave. License availability, DID portability, policy compatibility, emergency address configuration, and dependent service readiness are all validated before a single user is touched. Failures are flagged with specific remediation actions. The wave does not proceed until validation passes.
The orchestration engine executes the migration wave: assigns Teams Phone licenses, applies voice routing policies, configures dial plans, assigns DIDs, and sets emergency addresses — all in the defined cutover window. Each user's migration is an atomic operation: if any step fails, that user is automatically rolled back while the rest of the wave continues.
Post-migration validation confirms every user's phone service is operational. MigrationsIQ checks that licenses are active, policies are applied correctly, DIDs are responding, and emergency services are configured. A migration report is generated with pass/fail status for every user, every step, and every configuration element — ready for compliance review.
Enterprise organizations using MigrationsIQ report measurable improvements in speed, accuracy, and risk reduction.
What takes manual teams 6-8 weeks per migration wave completes in 3-5 days with MigrationsIQ. Automated license assignment, policy application, and DID porting eliminate the per-user manual effort that drives timeline bloat.
Every license, policy, dial plan, DID, and emergency address is applied programmatically. No copy-paste errors. No missed steps. No "I forgot to assign the calling policy" incidents that break phone service.
If any migration step fails, the affected user is restored to their pre-migration state automatically. No manual recovery, no extended downtime, no scrambling to figure out what went wrong while the business is without phone service.
MigrationsIQ handles the Teams Phone side of the migration — license assignment, policy application, DID porting, and configuration. It works regardless of the source PBX system (Avaya, Cisco, Mitel, NEC, legacy on-premises systems) because the migration orchestration focuses on the destination: Microsoft Teams Phone. The source PBX decommission is handled separately based on the specific legacy system.
MigrationsIQ is designed for enterprise-scale batch migrations. A single wave can include hundreds of users across one or multiple sites. The practical limit depends on DID porting schedules (carrier dependencies), cutover window duration, and Teams Phone license availability. Organizations typically migrate 200-500 users per wave, with multiple waves scheduled across a migration program.
If any step in a user's migration fails — license assignment error, policy conflict, DID issue — MigrationsIQ automatically rolls that specific user back to their pre-migration state. The rollback is atomic: only the failed user is affected, and the rest of the migration wave continues. The failure is logged with the specific step that failed, the error details, and the rollback confirmation, so IT can remediate and include the user in the next wave.
Pre-flight validation runs a comprehensive readiness assessment for every user in the migration wave before any changes are made. It checks: Teams Phone license availability (is there a seat to assign?), DID portability (is the number free and ready to port?), dial plan compatibility (does the dial plan exist and match the user's region?), calling policy readiness (are all required policies configured?), emergency address configuration (is the E911 address set correctly?), and dependent service availability (are the required Teams services operational?). Any failure blocks the affected user from migrating until remediated.
Yes. MigrationsIQ supports migrations to both Direct Routing and Operator Connect deployment models. For Direct Routing, the orchestration includes SBC trunk assignment, voice routing policy application, and PSTN usage record configuration. For Operator Connect, MigrationsIQ handles operator assignment, number provisioning through the operator, and Teams Phone policy application. The pre-flight validation adapts to the target deployment model, ensuring all model-specific prerequisites are checked before migration.
MigrationsIQ is a module within the TeamsCoreIQ platform. Once migration is complete, the users and their Teams Phone configurations are automatically visible in TeamsCoreIQ's ongoing governance capabilities — policy management, compliance monitoring, call quality analytics, and helpdesk diagnostics. Migration audit logs feed into TeamsCoreIQ's compliance reporting. This means migration is not a one-time event followed by a gap — it flows directly into day-2 operations and governance without a separate handoff.
