Location to store Global Settings? RRS feed

  • Question

  • Im trying to figure out what choice is the best one for my environment and based upon this picture http://www.shudnow.net/images/OCSR2Enterprise_09.jpg im a bit confused now. This will be a migration from LCS 2005 to OCS R2, so based solely on that, it has recommended System container. Here in lies my confusion, we have a mature exchange 2003 and 2007 environment in a resource forest which then points to Config container.. So what are peoples thoughts?

  • You should and can only migrate OCS Global settings from the default System Container in the root AD domain to the Configuration Partition *before* migrating LCS 2005 SP1 or OCS 2007 RTM to R2. This can be realized using the Microsoft Office Communications Server 2007 Global Settings Migration Tool.

    See a short write-up here.

    Do let us know if this claifies the issue. Thanks.

  • So I have to run the global settings migration tool no matter what? Or only if I want to use the config partition? Our domain controllers are all in the same location and we have 10 DC's so connectivity isnt an issue especially if it creates potential complications with the GSMT.

  • It is recommended best practice to move the OCS Global settings to the Configuration Partition for the various benefits cited. Once you start the R2 setup to perform an upgrade from LCS 2005 SP1/OCS 2007 RTM, the option to choose either the System Container (default in OCS 2007 RTM) or Configuration Partition is grayed out. If you proceed pass this point and complete R2 setup, it will no longer be possible to change the OCS Global settings location. AFAIK, there is no tool available to do this post R2 setup.

    Hope this helps. Thanks.

  • Jon, what is the layout and size of your AD forest/domain environment?

    The shift in recommended configuration storage locations between OCS and R2 is really due to the OCS server's availability to easily reach root domain controllers.  If you have a single site with all DCs in the same network segment then this decision really is mute as either configuration will perform about the same.  But if you have OCS servers in remote locations to DC from child domains and no root domains, for example, then you might want to consider moving the configuration data as it will be more readily available to the OCS servers (replicated on local child DCs and not just stored on remote root DCs).
