When Skype for Business replaced Microsoft Lync back in 2015, we thought that it would be around forever. Nothing remains static in the world of software, however. When Microsoft announced Teams just two years later, we all knew that Skype for Business would one day come to an end. Skype for Business Online will be formally retired on July 31, 2021, and thereafter all-new Office 365 users will be onboarded directly to Teams. Migrating from Skype for Business to Teams isn’t as straightforward as advertised. Although it can be quite simple, mechanically speaking, there are considerations that may place the simple avenue out of reach, especially for larger organizations.
