Hotels should first document what the existing system does, which equipment depends on it, how it connects to other infrastructure, and which operational processes have developed around it.

Teams should also identify integrations, cabling, network requirements, power requirements, room configurations (with hospitality TVs, HVAC systems, appliances, etc), support contracts, and any equipment that will remain after the upgrade.

Understanding these dependencies helps prevent situations where a seemingly straightforward replacement unexpectedly affects other hotel systems.
