Iguana 4.0 and later versions enable you to have more than one copy of the Iguana server running on your system. For example, you can use one copy as a test server and the other as the production server.

To install a second copy of Iguana on your system, you must:

• Unpack and configure your new server;
• Test your configuration to ensure that it is working properly;
• Register your server and ensure that any channels you have copied are correct;
• Install the new Windows service on your system.

The following sections describe how to perform these steps.

	If you use the method described in this section to install Iguana 4.0 or later manually on a system on which Iguana 3.3.2 is already installed, you may experience problems running plugins on your Iguana 4.0 server. See Problems With Plugins When Installing Iguana 4.0 Or Later Manually in an Iguana 3.3.2 Environment for information on how to resolve this problem.
