As long as you archive and properly mock the test server from hither on, you will form a basis to document changes dependent on the master branch. Usually it is cheaper to VPN the server in a locked virtual environment, so you see a full scope of the system. Vulnerabilities are getting scarier and efficient, thanks in part to manufacturers leaving vulnerabilities in the hardware/UEFI/BIOS/firmware. Right now, the biggest threat are GPUs with DMA and their undocumentation: enormous processing power that when clustered, can replicate innumerable vulnerabilities in one machine before the next cycle hits the CPU to address the bus.
