Shifting from Microsoft Teams to Slack as your organisation’s UC and collaboration platform is a momentous move.
While both platforms offer robust features, Slack can offer a more flexible, integration-rich ecosystem that many IT leaders and admins find appealing. However, a successful migration necessitates more than just flipping a switch—it demands a structured approach to minimise disruption and facilitate user adoption.
In this guide, we will explore the key benefits and challenges of making the switch and outline 10 critical steps to encourage a seamless transition.

Benefits and Challenges of Migrating from Teams to Slack
Benefits
- Enhanced Integration Flexibility – Slack’s open API and app directory pave the way for deeper integrations with a vast range of third-party tools, offering admins and IT leaders more customisation than Teams’ Microsoft-centric ecosystem.
- Streamlined User Experience – Slack’s intuitive, chat-centric interface and simplified navigation might lead to improved productivity and user satisfaction.
- Cross-Organisation Collaboration – Slack Connect can allow for more seamless external collaboration with partners and vendors, a feature that is sometimes more restrictive in Teams.
- Optimised for Asynchronous Work – Slack’s workflow automation, reminders, and threaded messaging make it a strong fit for hybrid and remote workforces.
Challenges
- Loss of Native Microsoft Integrations – Businesses reliant on deep Microsoft 365 integrations (e.g., SharePoint, OneDrive, Outlook) may need to completely reconfigure workflows or adopt alternative tools.
- User Adaptation and Training – Employees familiar with Teams may initially resist change, requiring thorough training and extensive onboarding efforts.
- Migration Complexity – Moving chat histories, files, and integrations between platforms is not natively supported and can require third-party tools or manual efforts.
- Cost Considerations – While Slack affords different pricing models, some organisations may experience increased costs compared to Teams, which is bundled with Microsoft 365.
Top 10 Things to Know When Migrating from Teams to Slack
1. Define Clear Migration Objectives
Before kicking off the migration, it's vital to establish clear goals. Are you switching for better integration, improved UX, or cost efficiency? Defining success metrics helps ensure migration is definitely the right move, track ROI, and align with business priorities.
2. Audit Existing Workflows and Integrations
Assess your current Teams environment: What apps, workflows, and integrations are essential? Identify Slack alternatives or migration strategies to prevent workflow disruptions. Leaders and admins should consider using Slack’s Workflow Builder for automation needs.
3. Plan Your Data Migration Strategy
Slack doesn’t natively import chat history from other platforms. Decide whether you need to preserve old conversations and files. Using a secure third-party tool like CloudFuze to extract, convert, and import essential data might be advisable.
4. Establish Governance and Security Protocols
Leaders and admins should ensure compliance with organisational security policies by configuring Slack’s Enterprise Grid (for large organisations). Set up admin controls, data retention policies, and permissions to maintain data integrity and security.
5. Structure Your Slack Workspace Efficiently
Slack’s workspace and channel structure differ from Teams’ team-based layout. Leaders and admins should prioritise designing a logical workspace hierarchy by mapping existing Teams structures into Slack channels, ensuring teams understand where to collaborate.
