Businesses need to stay up to date with the latest technology to succeed. Microsoft has decided to retire Skype for Business, and this has caused challenges for many businesses.

Microsoft Teams is the replacement, but it's more than just that. It's an upgrade that promises better features and functionalities that Skype for Business never offered. Teams integrate with the Microsoft 365 ecosystem seamlessly.

If your business hasn't yet switched to the new era of communication, don't worry. Skype for Business will continue until its official retirement date, giving you time to transition to Teams or even consider hosting your instance of Skype for Business Server.

Switching from Skype for Business to Teams migration can be daunting, especially one that has been used in your organisation for a long time. The challenges you'll face during this transition can vary based on the size of your current setup, the complexity of the move, and even the choice of a reliable partner to guide you through the process. 

We're here to help you make this Skype to Teams migration as smooth as possible, so please don't hesitate to ask for assistance.

Adopting Microsoft Teams?

This article is for you. Our article provides practical advice to make the transition smoother for a business. So, let's embark on this journey together and get ready to reap the rewards of a more efficient and forward-looking way of doing business.

10 things to know for a successful migration

Prepare your environment and organisation
In the journey from Skype to Microsoft Teams, begin by assembling your project stakeholders, including IT, project managers, and department heads. Next, define the project scope, specifying user numbers, timelines, and objectives. Understand how Skype for Business and Teams will coexist. Choose the migration path that suits your organisation, whether gradual or swift. You can choose between these two upgrade paths that can help with your migration:

  • Basic Upgrade (Cutover)
  • Pro Upgrade (Co-Existence)

Co-existence modes determine how Teams and Skype for Business clients interact during the transition. Consider whether you want a gradual transition or an immediate shift to TeamsOnly mode. Choose a mode that aligns with your organisation's goals and user experience.

Finally, conduct a pilot test with a small user group to address any issues early in the process.

Configure hybrid connectivity
Hybrid connectivity is the bridge that enables communication between your on-premises Skype for Business Server and Microsoft 365. Follow Microsoft's documentation to set up hybrid connectivity correctly.

Move users to Teams only
Microsoft has simplified the process of moving users to TeamsOnly, regardless of the version of Skype for Business Server you're using.

Follow Microsoft's documentation to execute this step smoothly. Users are automatically assigned TeamsOnly mode during the transition.

Complete the migration and decommission on-premises Skype for business
Once all users are successfully moved to Teams, you can decommission your on-premises Skype for Business deployment. This step finalises the migration, and you can start relying solely on Teams for communication and collaboration.  

Phone system and PSTN connectivity 
Phone System with Teams is supported after users are in TeamsOnly mode. Ensure that users' phone system needs are met. For PSTN connectivity, coordinate moves from Skype for Business on-premises to Teams with Microsoft Calling Plans or Direct Routing, depending on your organisation's requirements.

Important Considerations for on-premises Skype for business 
If you have Skype for Business Server on-premises, setting up hybrid connectivity is essential for migrating to TeamsOnly mode.

Ensure proper synchronisation of user attributes in Azure AD to manage users correctly in Teams.

Notify your users
Communication is crucial. Inform your Skype for Business users about the upcoming transition to Teams. Craft a notification strategy that focuses on the benefits of using Teams and addresses user concerns regarding the whole transition process.

Prioritise rollout based on stakeholders
Categorise your users into logical groups, such as core users, change champions, and support teams. Tailor your messages and approach for each group to ensure a smooth transition.

Implement customisable and scalable training
Training is essential to drive user adoption. Understand what users need to know and do with Teams. Customise training content based on user roles, competencies, and language. In addition, You may involve trainers and champions to deliver the company message effectively. Furthermore, You may offer a variety of training methods, from eLearning to live instruction, to accommodate different learning preferences and paces.
