The ITP/OnLine installer supports upgrading from any earlier version, starting from version 3.2.6. Upgrading from versions before 3.2.6 is not supported. During the upgrade process, the following dialogs are shown.
The Welcome dialog gives information on the software that you are going to install.
ITP/OnLine ASP.NET requires a virtual public directory in Microsoft Internet Information Services (IIS). This virtual public directory is automatically created by the ITP/OnLine ASP.NET installer if it does not already exist. If the virtual public directory was already created by an earlier upgrade, this dialog will not be shown. By default the virtual public directory name is "itppublic" and the corresponding physical path is <wwwroot>\itppublic, where <wwwroot> is the directory of the default web site.
Click to start the upgrade.
At the end of the upgrade process, the installer will offer to open the main ITP/OnLine ASP.NET configuration page. To finalize the upgrade, the operator should manually deploy all custom ITP/OnLine ASP.NET web applications that are listed on this page.
When the installation is completed, this dialog will appear: "Pressing the Finish button will end the installation." After the installation is complete, the operator should manually apply the authorizations described in chapter Authorization.
