SOME INDEPENDENT ADVICE
The real decision of whether to migrate groups of users to the new MOC 2007
client versus waiting until you can switch all users to the new MOC 2007 at
the same time comes down to how your users communicate. If your IM traffi c
is purely group or department based migrating smaller groups of users to
the new MOC 2007 client will work. However, if your entire organization
intercommunicates, and users get antsy and want to try out features of the
new MOC 2007 client, you should wait to switch over the client software

Planning Your Migration
from LCS 2005 to OCS 2007
As mentioned at the start of this chapter, the key to migrating from LCS 2005 to OCS 2007
is to follow a methodical process. The process begins by making sure you understand your
existing LCS 2005 environment so that when you perform the migration, you are migrating
all of the servers and server roles from LCS 2005 to OCS 2007. If you forgot you had an
LCS 2005 server hosting users and you do not include that server in your migration plan,
you may forget to migrate the users on that LCS 2005 system.
Identifying Existing LCS 2005 Servers
The fi rst step in the planning process is to identify which servers in the organization are
running LCS 2005, where the servers are located, and what server roles are currently installed
on the systems.
