Considerations when migrating from On-Premise SfB to a CCE

Introduction I thought I would note down some considerations when looking to migrate from an on-premise deployment of Skype for Business (SfB) to a Cloud Connector Edition (CCE).

If you do have issues (as I have had on a few occasions), you will probably want to capture some logs to investigate. Whilst not exactly the same, it’s not too dissimilar to the CLS Logging on Skype for Business Server. [Read More]
