I want to chang my server domain name from "machinename.domain.lcl" to "machinename.newdomain.lcl"
After that Arcgis Server recognize new domain name and started working. No problem.
But my Portal did not work. So i tried to change "machinename.domain.lcl" from portaladmin page but it is not allowed.
I tried to reinstall portal with new machine name and domain, this time my all portal content gone.
How can i change my domain name by saving my all portal content. Or how can i manually reinstall portal content from old folders to new installed portal folders.
