So I updated one of our Lync Server deployments to the latest release. Read through the installation notes and thought this is easy.
Snapshot of server taken and then run the update. All looks good and then reboot. Step two was updating the database. Simple task you would think. It failed with flying colours. Turns out you need 16Gb of free disk space for the update to run successfully. Once you have then the update of the database will run happily. This won’t be needed on the Edge server. It was applicable to the standard editions front end server.
Then run the Enable-CsTopology and the bootstrapper as per the installation instructions.
