A company intends to upgrade the operating system on every employee workstation during the next maintenance window. Before estimating the risk and effort involved, which of the following lists should the IT team compile FIRST to gauge the potential impact of the upgrade?
Warranty expiration dates for all desktop monitors
The current BIOS firmware versions for each workstation
A complete inventory of installed applications and their versions
The number of available power outlets in each office
An accurate inventory of all installed applications and their versions allows administrators to test and confirm compatibility with the new OS, identify software that requires updates or replacements, and plan remediation steps before deployment. While BIOS firmware levels and similar data are also important for hardware compatibility, they do not reveal whether business-critical applications will function after the upgrade. A common best practice is to inventory all applications currently in use as one of the first steps in the readiness assessment.
