If you want to upgrade to Skype for Business Server 2015, and don’t have a purely Lync Server 2013 environment, you will have to follow the migration path. The recommended path is to migrate from OCS or Lync Server 2010 to Lync Server 2013, then complete an in-place upgrade.
If you already have a purely Lync Server 2013 environment, you can skip straight to an in-place upgrade.

Andrew,
When I looked here (https://technet.microsoft.com/en-us/library/dn951396.aspx), it says I can move my users to SfB 2015 directly from Lync 2010 as long as I’m a “pure Lync 2010” installation. You are saying I have to go from 2010 to 2013, then to SfB 2015. I’m a little confused.
When I originally wrote this the guidance was a little unclear. Most of the information out there suggested the best path was to migrate to 2013, then in-place upgrade to 2015. Based on the article it looks like a migration directly to 2010 is supported, and this would fit with Microsoft’s statement that you can only have 2 versions at one time. I haven’t done this myself. I would just make sure Lync 2010 is fully patched before you start. Hope that helps a bit.
Hi Andrew,
do you have the steps on migrating Lync2013 to SFB2015 in parallel? i mean, not an in place upgrade. i will setup a new SFB infra then migrate all users. i cannot find any articles that are suitable for our requirements. ive finished installing prereq for my FE server and i have run the deployment wizards. after doing so, the Prepare AD is already completed in status but i did not do any prepare schema/forest or domains. is it normal ? i remember during my migration from Lync2010 to Lync2013, i did Prepare AD domain services before proceeding to the actual setup/topology creation. please help.
thank you.
Hey, I dont but the process is pretty much the same as it was from Lync 2010 to Lync 2013. That article is here – https://ucgeek.co/2014/05/lync-2013-deployment-migration-step-by-step/.
We are currently on O365/ hybrid mode for email already, 99% of our user base is using Exchange Online, dirsync is working properly and I verified we have Skype for business licenses (E3 License) but I am just not sure exactly how to go about it. We have Lync 2010 on-prem and one server with Lync 2013 Administrative tools
You can migrate from Lync 2010 directly to Skype for Business. Basically you deploy SfB side by side Lync 2010, migrate users, then finally decommission the old servers – https://ucgeek.co/2014/05/lync-2013-deployment-migration-step-by-step
