Step-by-Step Guide: Migrating from Skype for Business On-Premises to Microsoft Teams

Why Migrate to Microsoft Teams?

Microsoft Teams has emerged as the ultimate collaboration hub, integrating chat, video conferencing, file sharing, and app integrations. With Skype for Business Online retiring in 2025, migrating to Teams ensures continuity, enhanced features, and compliance with modern workplace demands.

Key Benefits:

• Unified communication and collaboration.
• Advanced security and compliance tools.
• Scalability for hybrid or remote workforces.

Prerequisites for Migration

Before starting, ensure your environment meets these requirements:

1. Assess Your Current Setup

• Inventory Skype for Business (on-prem) users, servers, and dependencies.
• Verify network readiness (bandwidth, QoS, firewall rules).
• Check compatibility with Microsoft Teams system requirements.

2. Plan Coexistence & Interoperability

Use Teams Upgrade Mode to run Teams alongside Skype for Business during migration. Learn more in our guide: Understanding Teams Coexistence Modes.

Step-by-Step Migration Process

Phase 1: Configure Hybrid Environment

1. Deploy Azure AD Connect to sync on-prem directories with Azure AD.
2. Enable Teams in Hybrid Mode using the Skype for Business Hybrid Configuration Wizard.

Phase 2: Pilot Migration

1. Migrate a test group of users to Teams.
2. Validate functionality (chat, meetings, PSTN calls).

Phase 3: Full Migration

Batch migrate users via PowerShell:

Move-CsUser -Identity "user@domain.com" -Target "teams.microsoft.com" -MoveToTeams

Update DNS records to route traffic to Teams.

Phase 4: Post-Migration Validation

• Test all features (e.g., meetings, guest access).
• Monitor via Microsoft Teams Admin Center.
