Hi, I am upgrading from 10.1 to 10.2.1. I used the default arcgis for the web adaptor name. (That way I didn't have to change my flex viewer layer's URL to each web service.) When I uninstall the web adaptor from the enterprise web server, will that delete the Virtual Directory to arcgis? Or do I have to go in web server software, after the uninstall, and remove the virtual directory name for arcgis? See Migration Checklist information on the Web Adaptor http://resources.arcgis.com/en/help/install-guides/arcgis-server/10.2/01nm/01nm0000001w000000.htm If your ArcGIS Server instance used the default name of arcgis and you want to maintain this in your upgraded site using the Web Adaptor, you need to do some preparatory work before you run the Web Adaptor setup. Using your web server software, remove the virtual directory named arcgis. Then delete the folder on disk that was holding the files for the ArcGIS Server instance, for example, C:\Inetpub\wwwroot\arcgis. (You may want to create a backup before you do this.) Finally, install the Web Adaptor and run the Web Adaptor configuration page. Or was this just for folks prior to 10.1? Thanks for any help! Janie
