Slack to Microsoft Teams Migration: A Step-by-Step Guide

Introduction:

The fact that you are reading this article means you have already decided to or at least seriously considering migrating from Slack to Microsoft Teams. It is fair to assume that you are looking for more clarity before taking a plunge or still contemplating if it is the right decision to make, here are a few data points to help understand that migrating to Microsoft Teams from Slack is the right thing to do. 

Why should you migrate to Microsoft Teams from Slack? 

Why pay double?

  • If you already have Microsoft 365 as the collaboration framework for your organization, it comes with messaging features in the form of Microsoft Teams 
  • Microsoft Teams offers a platform for teamwork and the opportunity to create a more open, fluid, and digital environment 
  • Microsoft Teams has all the features that Slack offers and the licensing cost for Slack would be far above Microsoft 365 licensing, with hardly any additional capabilities 

One Repository, simplified experience 

  • Content created in Microsoft Teams can be leveraged from other workloads of Microsoft 365 and vice versa 
  • Microsoft Teams files are stored in related SharePoint sites and in OneDrive, offering better search results and reducing duplicate content 
  • Slack operates in a silo and content created in Slack is not accessible from Microsoft 365 without custom integration. 

Unified user experience with other Microsoft 365 workloads 

  • Being a part of Microsoft 365 licensing, Microsoft Teams enjoys its generic infrastructural support like Security and Compliance, Information Protection, Auditing, Search, etc.

How does Microsoft Teams compare with Slack? 

Slack to Teams Migration

Larger Ecosystem 

  • Microsoft is committed to position Teams as the primary workspace for a unified user experience. Leveraging Microsoft Teams ensures your employees get the full advantages of that user experience. 
  • With Slack now being acquired by Salesforce, its roadmap for integration with Microsoft 365 workloads is yet to be seen 

Information Protection 

  • With Microsoft Information Protection (MIP) and Microsoft 365 Data Loss Prevention (DLP), you are guaranteed to have industry-grade protection for your content whether it is shared internally or externally 
  • Slack offers little control and visibility on what information is being shared and with whom. In Microsoft Teams, using Microsoft 365 Activity API, you can trace and analyze complete details of activities performed on content 

User Experience 

  • Microsoft Teams provides much superior document management experience with support for document versioning and co-authoring  
  • Support for audio & video communication as well as Microsoft Teams calling right from the Teams interface are great advantages  
  • Microsoft Teams tabs significantly improve user experience by presenting and highlighting the important content /apps right upfront 

Migration experience from Slack to Microsoft Teams

Now that we hope you are convinced about adopting Microsoft Teams, the next question is Can you import data from Slack to Teams? 

The answer is an absolute YES! Tools and expertise are available to import your content from Slack into Microsoft Teams with minimum to no disruption to your business activities and user experience. Depending on your preference, any, or all types of content from your Slack can be moved over to Microsoft Teams.

How do you move from Slack to Microsoft Teams?  

You must follow a strategy that would help you with making the right decision about what to move, how much to move, your migration timeline, cost of migration, and user experience. At an elevated level, your migration journey should include the following activities 

  1. Select the right migration partner. Doing it right is crucial for your migration journey as the rework cost is extremely high. The best option is to take expert help to guide you through every step of the migration
  2. Assess your Slack inventory. This would surface a multitude of information about types of content you possess, content freshness, usage pattern, active and dormant user groups or channels, and much more. The outcome would help you decide what is important to migrate and what you may consider for archival. 
  3. Put up a Migration Portal. The success of migration depends as much on involving the stakeholders throughout the journey as the process itself. Users impacted by the migration should have an upfront understanding of what they can expect and what is going to be their new experience. A migration portal with up-to-date information about migration schedule, status, source-target mapping, etc. will help users remain informed and would mitigate concerns if any. 
  4. Prototyping of Migration. The assessment outcome gives you insights into the diverse types of content, their ownership, and hierarchy. It is crucial to experience this content at the final target and resulting user experience. Prototyping exercise would help you try out different possibilities and arrive at the right option for your use cases. 
  5. Pilot Migration. With finalized directions achieved from the Prototype Migration, it is time to try your tools and processes in preparation for the main migration. In this step, you must handpick channels and groups to incorporate as much diversity as possible. Run the migration to understand the challenges, if any. This is followed by detailed validation of migrated content and tweak tools & processes as needed. The objective is to set up a fine-tuned process for the main migration.  
  6. Main Migration. This is when you migrate the decided content to their final target (Microsoft Teams) location. You also perform through validation of the migrated content.  
  7. Cutover Migration. As the overall migration takes time (few weeks to months), you support business continuity by allowing Slack usage as usual. Content created during the migration process would then be moved over to Teams over a short and quick cutover migration. This is typically scheduled over a weekend to avoid downtime.  

Understanding of Slack Containers & Content 

Slack comes with a container hierarchy and content stored inside those containers. Containers include Workspace, Channels (Public and Private) and Direct Messages. While Workspace is the parent container of all other containers, Channels host group-specific chat messages. Slack direct messages are one-on-one messages between users. For moving to Teams a proper mapping strategy would be defined for  

  • Public Channels 
  • Private Channels 
  • Channel Chats with history 
  • Files associated with Channel Chats 
  • Direct Messages 
  • Files associated with Direct Messages 
Content mapping with features and functionality 

Microsoft Teams is designed with a similar container hierarchy as that of Slack. However, there are important feature differences, and it is important to understand how you would map source and target location for the best user experience. 

  Slack Features Migration Mapping MS Teams Features
Channel Channels to hold most of your conversations with other members. They can be organized around anything — departments, projects, or even office locations, and you can create as many as you need. Slack channels can be mapped to Microsoft Teams.

Unit block of conversations among Channel members. Root post and replies make a thread. Posts can have rich content with embedded images and attachments Post supports reactions and emojis Channel messages with replies move under one of the Teams channels. Messages would be retained as an individual entity Messages would retain any embedded images and attachments. Messages would also retain their original authorship information and timestamp Microsoft Team supports an almost identical set of features and functionality for channel messages as that of Slack
Direct Messages One-on-one and group messages fall under this category These are conversations outside any channels No direct mapping capability to Teams Direct Message. Customized repository and rendition in Teams via custom App Slack direct messages are rendered separately from native Teams Direct Messages. Similar user experience and search capabilities

Apps Slack has developed a rich ecosystem of 3rd party apps. Most of the Apps use adaptive cards for user interaction Many 3rd party apps also developed their Teams versions. Some apps can be linked to their repositories from Teams. Others need custom logic for migration of existing messages Microsoft Teams 3rd party app ecosystem is growing rapidly as well. Most of the popular apps are already in Teams, providing identical feature sets.
    Additionally, Microsoft Teams has native support for other Microsoft apps like Word, Excel, PowerPoint.
