Importing a Certifi cate into OCS 2007
Once you have exported the certifi cate from the LCS 2005 server, you need to install a new
OCS 2007 server as an edge server into the organization (we cover this process in the following
section). Because the goal is to have the new server have the same name as the old server, you
will need to uninstall the old LCS 2005 server prior to installing the new OCS 2007 server.
This is tricky, as you don??™t want to drop an LCS 2005 server until you know the new OCS
2007 server is working properly. This is why this process of exporting and importing certifi cates
is usually done when an organization has more than one LCS 2005 access proxy system and
can easily afford to uninstall one LCS 2005 access proxy to build up a new OCS 2007 edge
server when it has other LCS 2005 access proxy systems actively routing inbound and outbound
communications.
