We are planning to develop webApps using ArcGIS Online/Portal and publishing in different browsers/mobile devices. In this regard, We segregate as two modules.
Module No: 1
Use the Templates which is available in ArcGIS Online and publish the apps.
Module No 2:
The newly created apps can be uploaded to ArcGIS Online/Portal accounts. As well as We can download the existing templates from the ArcGIS Online account, modified according to needs and reupload to ArcGIS online account.
We want to know Module No 2 approach is possible or not?
