There's no automatic process that Installshield can provide here unfortunately.
The convert options is only available to convert from Basic msi to installscript and InstallscriptMSI to Installscript and not vice versa is not possible
However Flexera does have a product called Adminstudio which includes functionality called the Repackager. This will allow you to capture an installation and convert that to an .msi and Basic MSI project. You can then convert the Basic MSI project into an Installscript MSI project using Installshield.
Be aware however that this repackaging process will not retain any Installscript logic, it will only capture what happens during the installation process.
If you don't want to go down this route, then it would be a manual process of creating a new project from scratch.
