How to change Portal URL in Web AppBuilder App ?

[RogerF]

I have to change Portal URL due to organization wide domain change. I have Web AppBuilder Developer (WABD) deployed in the environment. I made changes to portal URL to following places

1. C:\<path>\arcgis-web-appbuilder-2.x\WebAppBuilderForArcGIS\server\db\

   Changed "portalUrl" in the app file for all the apps.

2. C:\<path>\arcgis-web-appbuilder-2.x\WebAppBuilderForArcGIS\server\apps
   Changed portalUrl in config.json file under each app

I restarted ArcGISWebAppBuilder service to make sure changes take effect. But I am unable to see app list when I open WABD stem app.

Is there anything else I am missing. ?

Roger,

   You need to update the server/signininfo.json file portalUrl as well.

Yes I did that as well. I forgot to mention that.

That should be everything... I guess you need to give tech support a call.
