If you are
not using an LCS 2005 director, just enter the LCS 2005 server name of the system
that is the next hop.

348 Chapter 11 ??? Upgrading to Offi ce Communications Server 2007
Redirecting Internal LCS 2005
Servers through the New Edge Server
Once the new OCS 2007 edge server has been installed, it is actually doing nothing on the
network. Because no inbound or outbound servers acknowledge that this new server exists,
the server is effectively installed, but not processing any communications. When choosing to
switch over inbound or outbound communications to the edge server, the standard process is
to switch over outbound communications to the new OCS 2007 edge server. You do this by
directing the outbound communications from an LCS 2005 director server or an LCS 2005
front-end server.
When you make a relatively simple confi guration change on either the LCS 2005 director
or the LCS 2005 front-end server, all outbound communications will now go through this
new OCS 2007 edge server.
