I have a SharePoint 2010 Setup in a VM. And Content DB of central admin of this server, say "Server A" resides on "DB Server 1". Now i clone the VM and create another copy say "Server B". I changed IP, renamed servername and also corrected Alternate access mapping. But how do i select different database for central admin for "Server B"?As it still points to "DB Server 1" and hence "Server A" central admin opens up even if i click central admin on "Servr B"?
Here is what you need to do:
Create an isolated network
Clone an existing Domain Controller into the isolated network
Forcefully remove all other DCs from this cloned domain
Shutdown SharePoint Server(s) + SQL Server, create copy.
Bring copy up in the isolated network. Never, ever let the copy of SharePoint 'see' the production network.
I would highly recommend you have to recreate the configuration database. If i am not wrong, Cloning is not supported( COnfig DB). You have to config wizard and recreate the configuration database and provision central admin.
Here is an article may help your situation. http://spnotepad.blogspot.com/2011/03/how-to-clone-sharepoint-2010-hyper-v-vm.html
