Migrating Lync Users

Start course
1h 10m

Microsoft 365 represents a combination of Office 365, Windows 10 and Enterprise Mobility offerings – providing the most complete set of SaaS technologies that Microsoft has to offer. With Microsoft 365, organizations can deploy a complete solution encompassing both devices and applications, along with applying security and compliance policies to protect the entire suite.

This course will help you as you plan your migration of users and data to Microsoft 365, including planning your identity and authentication solution, and the on-premises infrastructure needed to support your migration. We’ll also help you understand and identify your business requirements and use cases, to help drive your decision-making process when planning to transition your infrastructure to the Microsoft cloud. We’ll spend some time focusing on networking and discuss some of the networking decisions that need to be made to ensure an optimal migration experience, as well as the best experience for your users after migration.

This course will also help you to identify which data needs to be migrated to the cloud, and what the best migration method will be based on your scenario – we’re also going to cover the different types of user identities, how your users will authenticate, and how that’s going to affect your migration planning.

In addition to talking about these different components, we’re also going to run through a few demos – showing you some of the practical steps involved, along with some tips and tricks we’ve picked up along the way. 

Learning Objectives

By the end of this course, you should be able to:

  • Plan a Microsoft 365 Implementation, including the supporting infrastructure
  • Plan your identity and authentication solution, both on-premises and in the cloud

To get the most from this course, you should have a general understanding of networking & server administration as well as IT fundamentals such as DNS, Active Directory and PowerShell.


Migrating users from Lync or Skype for Business on premises is fairly straightforward provided your environment is not that complicated. If all you're using Lync for is IM and Presence, and you have and Edge server in place, you can configure a hybrid Skype environment and move your users from the on-premises pools to the Skype for Business Online pools. 

If your users are configured for Enterprise Voice on premises, you'll need to coordinate updating their voice configuration when you move them online, either using the Microsoft Calling Plan configuration or continue to use your on-premises PSTN provider with Direct Routing. You can also migrate users to Skype for Business Online with other telephony capabilities, but since this removes functionality, it's not an ideal scenario. The bottom line for Lync and Skype migrations is that they are pretty simple to do if you have your pre-requisites in place for configuring hybrid and you don't need to do anything complicated. If it's not feasible for you to configure the Edge server for a hybrid migration, your only other option is to disable your users on premises and enable them for Skype for Business Online. 

Note that while you're doing this, you'll need to make sure that your DNS records are updated so that when users attempt to sign in to Skype for Business, they'll be redirected to Skype for Business Online and not the on-premises Skype server.
