Hi. I have a portal for Arc GIS federate and IWA autentication. I have that to migration, so I want to know ESRI has tools for doing the migration.
Is it posible that not lose settings such as look an feel , groups, user, galleries …?
Depending on your scenario, you might take a look at the Admin Tools from GEO Jobe
I have used the AGOL ones a little bit. They now have a Portal version that supposedly lets you copy from AGOL to Portal, dev to test to prod, etc...
Maybe it would work for you? Not sure if it can be used in an upgrade case (say from 10.2.x Portal to 10.3.1, etc..)
While that listing if for AGOL it should get you in contact with the company regarding the Portal version.
The Portal version is quite new I believe. Good luck.
Yes Paul the Admin Tools for Portal is now available - You can see the Functionality Matrix here -Admin Tools New - Geo Jobe
Also, we just released the ability to view Item's dependencies across your organization. Now available in Pro & Portal.
Hope this helps..
