I used to run Skype for Business on-premises (ever since Lync Server 2010) and every year I was struggling with SSL Certificate renewal. Last time (few weeks ago) it didn’t work as expected (every now and then I could not respond to message) I decided to move to Skype for Business Online.
Since not too much SfB enabled users were involved I decided to decommission SfB on-premises first and then enable SfB in Office 365 (user accounts were synchronized from on-premises Active Directory to Azure Active Directory).

- PowerShell RTM version (6.2.9200.0) or later
- SQL Server 2012 SP1 or later
- Kb2533623 Windows Server 2008 R2
- Kb2858668 Windows Server 2012
- KB2982006 Windows Server 2012 R2
I’m running Windows Server 2012 R2 on all my servers, so the only updates I have to apply is the Cumulative Update for Lync (to be safe, the May 2015 Cumulative Update (https://support.microsoft.com/en-us/kb/3051949) and the SQL Server 2012 SP1 update.
