If you would like to have a second In-house EP installation which you are going to use for testing purposes ONLY, then you can make a copy of your existing one and set up a 'clone' on a base of it on the same server. Please be aware that there is no way to easily rollback any global changes made on a production EP account, thus the ONLY meaning of having a second one is a firsthand acquaintance with In-house installation benefits and ability to perform tests of the functionality.

In order to 'clone' your EP account you need to do the following.

Preparation:

1) Back up your existing EasyProjects database using the SQL Server Management Studio.

Locate your Easy Projects database, right-click on it and select Tasks - Back Up.

2) Restore a database from the backup under a different name (e.g. "EasyProjects-test") on the same SQL server using the SQL Server Management Studio.

Click on Databases and select Restore Database.

3) Create an empty folder (e.g. "EasyProjects-test") at 'c:\inetpub\wwwroot\' where EP files of the second instance will be located.

4) Create a separate application pool (e.g. "EP-test") in IIS Manager, choose .NET 4.0 and "Integrated" mode for it.

5) Create a new Web site/application (e.g. "EasyProjects-test") in IIS Manager and choose just created application pool to run with it.

6) Make sure you have downloaded the EP installer of the same version as your original EP In-house installation from:
http://www.easyprojects.net/downloads

Installation:

1) Run the EP installer in the 'Upgrade' mode.

2) Browse to choose the path to the folder where EP installation files will be created (e.g. c:\inetpub\wwwroot\EasyProjects-test) at the corresponding step of installation process.

3) Enter 'sa' user login credentials and choose the name of the restored database (e.g. EasyProjects-test).

4) Choose the virtual folder/application (e.g. EasyProjects-test) created earlier in IIS.
Finish the installation.
