Merge 2007 or 2007 R2
Topology
Step by Step: How to install Lync Server 2010
After you have installed Lync Server 2010, Lync users should communicate with each
other without any problem. But in a co-existence scenario you need to merge the
OCS 2007 R1\R2 and Lync topologies. Otherwise OCS 2007 R1\R2 and Lync users wont
be able to communicate with each other.
The Merge feature
allows you to import information from your previous Office Communications Server
environments, and integrate it into a consolidated view alongside your Lync Server
2010 deployment.
To complete the process,
install WMI Backward Compatibility Package on the Lync Front End Server (or the
server from where you’ll run the merge operation).
From your installation
media, navigate to \SETUP\AMD64\SETUP\OCSWMIBC.MSI.
Install OCSWMIBC.MSI.
After you have
installed WMI
Backward Compatibility Package, start Topology Builder on the Lync Server.
Click Start, click All Programs, click Microsoft Lync Server 2010 (RC),
and then click Lync Server Topology Builder.
Select the option to Download topology from existing
deployment and then click OK.
In the Actions pane, click Topology
and then Merge 2007 or 2007 R2 Topology.
Click Next to continue.
In Specify Edge Setup, do one of the following:
-
If you have Edge Servers
in your Office Communications Server 2007 R2 environment, click Add and then
enter the information about your Office Communications Server 2007 R2 Edge Server
environment.
-
If you do not have Edge Servers in your Office Communications
Server 2007 R2 environment, click Next to move ahead without providing edge
info.
In Specify Edge
Setup, click Next.
In Specify Internal
Edge Settings Information, enter the relevant information for your Edge
pool’s internal FQDN and ports as needed, and then click Next.
In Specify External
Edge, enter the Web Conferencing FQDN information for your Edge Server and
then click Next.
In Specify Next
Hop, enter the FQDN of the next hop location in your environment, and select
whether it is a Front End pool or a Director. Then click Finish.
In Specify Internal
SIP port setting, select the default automatic discovery setting (that is,
if you did not modify the default SIP port). Change as appropriate if you are not
using a default port of 5061.
You may receive following
error if SIP domains configured in OCS setup and Lync setup differ. You need to
ensure that you have exactly same number and name of SIP domains configured in both
environments.
The value of default domain
in "Office Communications Server 2007"
/ "Office Communications Server 2007 R2" is "sip.in". The value of default domain
in Lync Server 2010 (RC) is "sip.com".These
two values need to be equal before you can continue merging the topology.
After successful merge operation,
you will see an additional site “BackCompatSite” in the topology builder.
Now, run the
“Publish topology” wizard. From the Actions pane, select Publish Topology, and then click
Next
When the Publishing
wizard completes, click Finish to close the wizard.
From the Microsoft Lync Server 2010 program group,
open Lync Server 2010 Management Shell
The final migration step requires running the Import-CsLegacyConfiguration
cmdlet. This cmdlet commits the changes from your legacy environment to Lync Server
2010.
Run Import-CsLegacyConfiguration.
That’s all!!! The legacy
and Lync setup are merged. This will enable the co-existence of Lync setup and OCS
2007 R1\R2 setup.
Note: You can
either have Lync and OCS 2007 R1, or Lync and OCS 2007 R2. Having Lync 2010, OCS
2007 R1 and OCS 2007 R2 setup together is not supported.
