What I'd do is
- Install the software in the new hardware
- Backup the file C:\ProgramData\QlikTech and any other folders with QVDs and QVWs as set in the QMC in the older hardware.
- Copy them to the new hardware, overwritting the empty folders (the new hardware does not have services started yet).
- Shutdown QlikView Services in the old hardware.
- Reboot the new hardware.
If you are not moving from a major release (for example, from 9 to 11), that should be all.
Hope that helps.
User and document license data is stored into .Meta and .PGO files. As long as you don't remove these, you will keep your data as you have it now. Server License data is stored into the C:\ProgramData\QlikTech folder by default, if it's only a change of the name of the server in the QMC, you shouldn't make any other change.
As usual, backup al your contents before any action.
