Upgrading to Office Communications Server 2007 ??? Chapter 11 357
If you had only LCS 2005 Standard Edition servers in your environment (not LCS 2005
Enterprise Edition systems), you are done. You have successfully migrated from LCS 2005 to
OCS 2007, and have successfully removed LCS 2005 from the environment with the removal
of the last LCS 2005 Standard Edition system from the network.
Removing LCS 2005 Enterprise Edition
If you have LCS 2005 Enterprise Edition systems in the environment, the removal process is
a little more involved, as you have to remove servers within an enterprise pool before you can
delete the pool. However, the process is effectively the same, and it requires that you follow
these steps:
1. Follow the steps outlined in the ???Removing LCS 2005 Standard Edition??? section
to remove each server.
2. To remove the Enterprise Edition of LCS 2005, right-click the pool and then click
Remove pool.
