To download and install SQL Server 2012 SP1, download the SQLEXPR_ењ†4_ENU.exe from. Sykpe4B Server 2015 Standard Edition needsВ at leastВ SQL Server 2012 SP1 or higher so if the server was installed with Lync 2013 server, most likely the version is SQL Server 2012 which means it needs to be updated first. Note that for a fresh install of Skype4B ServerВ 2015, the only supported OS is Windows Server 2012 R2, however for an in-place upgrade, we can use the existing OS that Lync 2013 server is on, but the following hotfixes are needed depending on the OS:

We cannot invoke-CsPoolFailover during the in-place upgrade.В In addition, we should first upgrade Front-End Pools before upgrading other pool types such asВ Edge Pools, Mediation PoolsВ and P-Chat pools etc. If pool pairing is configured for these 2 pools then it should remain as paired pools during the entire in-placeВ upgrade process.

During the in-place upgrade, we move all users from one pool to the other, then upgrade the first pool to Skype4B, before moving the users back, and then repeat for the other pool. So in order to upgrade to Skype4B server without any user downtime, we will need at least 2 Lync 2013 server pools with a single pool having enough capacity to handle workloads for all users. Its important to note that all Lync 2013 servers in a pool must be upgraded to Skype4B together, ie no partial upgrading of servers within a pool.
