Hi Miriam,
What I suggest is first copy the .sln file and rename it then you can also remove projects which you don't need. You can easily package files for deployment without any C# source code using Unleash It. You point it at the Web folder for the source and give it a target folder where it will copy the needed files (without any C# source code). After the files are copied to your target folder you can further remove any .xml files from the /bin folder, and you can delete non-MS SQL scripts from beneath /Setup/application/mojoportal-core/SchemaInstallScripts and /SchemaUpgradeScripts
After that the only thing you should do to prepare the package for instllation is in Web.config change <compilation debug="true" to false.
Hope it helps,
Joe
