Unfortunately, there are no out of the box tools for cloning an ArcGIS Enterprise deployment. There are python scripts you can use:
These would get you most of the way, but services are not cloned so you have to republish those. You'll also need to then update any references in your webmaps to point to the correct services URLs, which can probably be done when you're copying the items.
What is your use case for cloning? Are you attempting to create a staging environment?
Thanks Jonathan, I want to save some time by just cloning a clean install versus installing all the components 5 times.
Indeed the services are the only one left behind. I was able to make all the other cloned pieces to work, but the old services address is being invoked.
The reference does not include service migration..only users, groups, contents.
Are you referring to the reference in webmaps? While you're looping through the content, if it's a webmap item, you should loop through the operational and basemap layers and update the URLs.
