4.3.1 Changing the Operating Environment for WSUS

To change the operating environment for Microsoft Windows Server Update Services (WSUS), perform the following setup operation.

Adding a WSUS server

Install a Systemwalker Software Configuration Manager agent on the WSUS server to be added.
Implement changes to the configuration between WSUS servers by referring to the WSUS manuals.
(For example, changing upstream or downstream servers, migrating the managed computers, etc.)
To take a business server that was being managed by an existing WSUS server and have it managed by an additional WSUS server, use the following procedure to migrate the managed computer:
1. Delete the business server to be migrated from the list of computers managed by the existing WSUS server.
2. Execute the connection destination repository server registration command (swcfmg_register_repsv) on the business server that has been migrated in order to register the additional WSUS server.
  Example:
  swcfmg_register_repsv.bat wsus -to 10.10.10.10
  Refer to the Reference Guide for information on the connection destination repository server registration command (swcfmg_patch_importrpmpolicy).
Register the additional WSUS server on the admin server.
Modify the discovery definition file.
Example: Adding the WSUS server with IP address 11.11.11.11 to an environment where only the WSYS server with IP address 10.10.10.10 had been used
```
<?xml version="1.0" encoding="utf-8"?>
<Discovery>
  <RepositoryServers>
    <WSUS>
      <entry key="enable-wsus">true</entry>
      <entry key="ipaddress">10.10.10.10</entry>
    </WSUS>
    <WSUS>
      <entry key="enable-wsus">true</entry>
      <entry key="ipaddress">11.11.11.11</entry>
    </WSUS>
  </RepositoryServers>
</Discovery>
```
Refer to the Reference Guide for information on the discovery definition file.
There is no need to restart Systemwalker Software Configuration Manager.

Removing a WSUS server

Uninstall the Systemwalker Software Configuration Manager agent from the WSUS server to be removed.
Implement changes to the configuration between WSUS servers by referring to the WSUS manuals.
(For example, changing upstream or downstream servers, migrating the managed computers, etc.)
To take a business server that was being managed by the WSUS server to be removed and have it managed by another WSUS server, use the following procedure to migrate the managed computer:
1. Execute the connection destination repository server registration command (swcfmg_register_repsv) on the business server that has been migrated.
  Example:
  swcfmg_register_repsv.bat wsus -to 10.10.10.10
  Refer to the Reference Guide for information on the connection destination repository server registration command (swcfmg_patch_importrpmpolicy).
Delete the WSUS server to be removed from the management target for the admin server.
Modify the discovery definition file.
Example: Removing a WSUS server with IP address 10.10.10.10
```
<?xml version="1.0" encoding="utf-8"?>
<Discovery>
  <RepositoryServers>
    <WSUS>
      <entry key="enable-wsus">false</entry>
      <entry key="ipaddress">10.10.10.10</entry>
    </WSUS>
  </RepositoryServers>
</Discovery>
```
Note: Omitting the <WSUS> element has the same result.
Refer to the Reference Guide for information on the discovery definition file.
There is no need to restart Systemwalker Software Configuration Manager.
