We have configured Portal for ArcGIS and federated with Server but some issue is getting while upload feature as Excel and Shape file.
We try to resolved the issue but we found that datastore is not configured properly so, we are unable to do this thing.
Please let me know while reconfiguring the Datastore, is it required to un-federate and federate it again?
There's no need to unfederate Server before registering the Data Store. Once you've installed and configured ArcGIS Data Store with your Server, you can simply set the federated Server as the hosting server through the Portal home page.
