I am studying to take the OCS R2 certification and this book has been an invaluable resource. I highly recommend it to anyone studying for their OCS certification.

The resource kit for R2 is very similar to the R1 version - it is a very technical reference on the servers, roles, services, ports and communications mechanisms to the latest version of OCS. In that, it is written for those with on-hand experience with Microsoft server OS deployments such as Server 2003 and Server 2008. This book is not a book for beginners on OCS. In my opionion, there isn't a good written published reference for beginners - stick with the Microsoft white papers and TechNet articles. If your job is to design, architect OCS R2, this book is very valuable and will provide the process and procedures for completing your design. Deployment tasks are treated a little more lightly; while they are covered, the specific task-by-task details are not provided. That, again, is left to the white papers Microsoft has written well on the subject. As far as migration from OCS R1 to R2, the pages covered are from 659 to 662. Only a few pages - but the process to migrate is depicted in the pages. Migration from LCS or OCS R1 is a coexistence process as you will likely deploy OCS R2 on net-new hardware along side the existing legacy product. This allows easy migration by simply associating the legacy SIP-enabled users to the new system.
This reference is well worth the purchase price. This, along with the Microsoft-provided technical references will steer you in the right direction for OCS R2.

This book tells you nothing but theory. If you actually want to install, deploy, and manage an OCS R2 installation, look elsehwere. Even more insulting, this book *doesn't even mention "upgrade"*. If you have an OCS 2007 R1 install and want to upgrade to R2, you'll end up like me... up the creek building your own boat and carving your own paddle, because Microsoft has ZERO documentation on it, and honestly, it can't be done anyways. I spent 8+ hours with their TOP OCS support person trying to do this, and it was an epic fail.
