Thank you for letting us know about this. This looks like a bug in the way we're generating the site configuration probably related to a specific server-level configuration section/setting on your machine (hence why it fails for all the sites on the server). To help us figure out where this is occurring, could you please run the below command for one of the sites and send us the output anonAssessmentInfo.json file (you could share a pointer to the file or email to me at my username @microsoft.com if you prefer)?

1. Find out the path for the installation of iisConfigurationHelper.exe: Right-click the AppServiceMigrationTool desktop shortcut and select Properties. Look for the path in the "Start in" value (should be something like: C:\Users<yourUserName>\AppData\Local\Programs\azure-appService-migrationtool).
2. Open an admin command prompt and go to that location with added "\iisConfigAssistant": C:\Users<yourUserName>\AppData\Local\Programs\azure-appService-migrationtool\iisConfigAssistant
3. Run below command and send us the output - note that siteName should exactly match how site name appears when you run iisConfigAssistant.exe GetSiteList:

iisConfigAssistant.exe GetSiteAssessmentData "[siteName]" true [pathToMappingFile] > [pathToAnonAssessmentInfoFile]

example:
iisConfigAssistant.exe GetSiteAssessmentData "Default Web Site" true C:\TEMP\deleteThisDontShareIt.txt > C:\TEMP\anonAssessmentInfo.json

I'm getting the same error while testing IIS site placed on IIS 7.5 (Windows Server 2008 R2)

There are changes in latest v1.0.1 Migration Assistant that were made to address the errors seen by @RiccardoGMoschetti and @philipccwong - please try using this latest version and let us know if you are still seeing these issues!

@KarolLipnickiLX : please also try using the latest version. From the error message you posted it looks like there might be a syntax issue in the command of specifying the sitename using different casing than the sitename was listed using the GetSiteList command - unfortunately this command is very case-sensitive. If you still have issues when using the v1.0.1 version then please let us know.

Closing issue - please open a new issue if this is still seen using the v1.0.1 or latest release.
