We have a client with an existing 10.9.1 installation of ArcGIS Enterprise on one VM (Windows Server 2016). They are procuring a new VM and would like to do a clean install of 11.3 on this second VM (Windows Server 2022).
They do have extensive data on the 10.9.1 installation, however.
Is there a path where we can back up their hosted feature layers and/or other content from the 10.9.1 installation and restore it to 11.3?
From this page, it looks like WebGISDR cannot be used, since the versions of ArcGIS Enterprise do not match.

"The WebGISDR utility records the software versions of the ArcGIS Enterprise components when you create a backup. The deployment to which you restore must be at the same version it was when you created the backup. Additionally, you must restore to the same type of operating system. For example, you cannot create a backup of an ArcGIS Enterprise deployment on Linux and restore it to Windows machines."
