We recently upgraded our production vault OS and SQL, and since we are about to move from 2017 to 2018 I need to create a new test vault. Our previous test vault was something that was set up when we initially migrated to PDM by the VAR we were using. It was quite minimal but had the same work flows, settings,and mirrored the way the servers were set up. My question is what are you using for a test setup and what are the best practices. Our production vault is on a VM now, and my IT department says no problem to set me up another VM to build it on, but may not like giving me another TB to play with to do a complete copy. Thanks in advance for your help.
