Is there a way to pull a list of the client versions in a report format?'
I'm trying to see which servers are not up to date on their client
The easiest way is to run the Computer Status report under Monitors >> Logs
You can export to CSV and drop into Excel and filter on the client version column and get what you need.
I think I'd prefer to run the Report Client Status=>Client Inventory Details. It lists client version, protection versions, OS, and a whole lot more. It can also be printed, saved, or copied/pasted into Excel.
