Ok, so this would be tricky...
I have a machine where a standalone ArcGIS Server (ver. 10.3.1) is installed. There, I have many published services.
I had used in the past the backup and restore utility to port an ArcGIS Server site from one machien to another with success.
Now, the situation is: my other machine has an ArcGIS Enterprise (ver. 10.6) installed with the ArcGIS Enterprise Builder (if that matters). This implioes that the server is federated with the Portal, that I have
I tried to use the backup/restore procedure in this occasion as well, but I ended up having my server not working anymore and I am now reinstalling from scratch.
Is there a document or similar which highligts the procedure/best practice to do this?
Or should I avoid using the Builder, installing the server component only, and then following the procdedure of Migrating standalone ArcGIS Server to ArcGIS Enterprise | ArcGIS Blog?
