Hi @viveksundararaj, thank you for letting us know about this. This sounds like an issue that was fixed in the currently available Preview version of the tool. Would you be willing to try that version and let us know if that works? It would be the "App Service migration assistant for Java on Apache Tomcat (Windows—preview)" on https://azure.microsoft.com/en-us/services/app-service/migration-assistant/ - this includes the IIS app migration experience in addition to the Preview TOMCAT app option.
If that doesn't resolve the issue, would you be willing to share a detail like the site name you used for the migration so we could try to associate backend logs for the particular site migration and see if we can tell what happened from that? You could even create a "throwaway" site just for the migration attempt.
@krolson , we almost facing a similar issue after the above migration in progress wizard, it turns to a blank screen, we don't see a message about migration completion, and when we access the target azure web app with a private endpoint or public URL site is not up. Do you suggest us to use the above preview PowerShell way to try migration? does the PowerShell script modify any config on the source IIS server or involve any downtime on the source IIS site

@padevadi, I would advise you to try the suggestion of Krolson. The preview version (App Service migration assistant for Java on Apache Tomcat (Windows—preview) did work out on my case.
Thanks, @viveksundararaj . But when I am running Generate-MigrationSettings.ps1, I am receiving the below error message Site package results file: Exception of type 'System.OutOfMemoryException' was thrown
I did upgrade the mem on the server from which I am running the script as well as upgraded the pagefile
Hi @padevadi - thanks for the comments here!
We haven't seen that particular error for the Generate-MigrationSettings.ps1 before - couple questions/thoughts/options:
$PackageResults = Get-Content $SitePackageResultsPath -ErrorAction Stop | ConvertFrom-Json
@krolson, I copied the package zip and json output to another system and executed the invoke migration step from that system. Migration is successfull now.
Investigative information
Repro steps
Just run the Azure App Service Migration Assistant Tool. During the assessment, the tool found 2 gave 2 warnings only.
Expected behavior
An Azure WebApp must be provisioned and the content of the on premise website must be moved to Azure WebApp.
Actual behavior
A new Azure WebApp is being provisioned but the content of the on premise website is not being moved to Azure WebApp. The tool hangs during the migration of web content and a blank screen appears.
