Making the Move from Microsoft Teams to Slack

For a lot of enterprises, Microsoft Teams arrived by default — bundled in, already deployed, easy to justify. The organizations moving to Slack aren’t looking for a better chat app. They’re looking for a better way to work.

Slack connects your conversations, tools, and automations in one place, and it doesn’t ask you to abandon your Microsoft 365 investment to do it. Outlook, SharePoint, and OneDrive work alongside Salesforce, GitHub, ServiceNow, and the rest of the tools your teams already rely on.

The migration itself is more manageable than most IT leaders expect. A three-phase approach (Prepare, Maintain, Transform) guides organizations from Day 1 setup through full adoption. Most teams don’t need to port over years of message history. What they need is a foundation built for how work is actually evolving: persistent, searchable, and ready for AI.

This guide is for IT leaders who are ready to understand what a move to Slack really involves and what becomes possible on the other side.
