OK, I have restored today a QlikView Server v11 SR2. I simply:
- installed the QlikView Server application on the new server
- stop the QlikView services
- copy all files and folders from the old server <SystemDrive>:\ProgramData\QlikTech\
- start the QlikView services
I should reboot one time (because some services was registered with the old server's name).
But it work, my new server is now running with all the configuration, documents, users, tasks, etc.... that were on the old server.
