Hi everyone! At my job we have an old Mac Pro 3,1 that has been used for years and year. Its primary function is to act as a server I can dial in from a different computer on the same network. The Mac Pro has about 4 drives, one is the main drive we use to hold the media our company produces. At one point we had Mountain Lion Server installed with a VPN setup in order to access the iMac and server from anywhere outside the office. I've run into two issues now: 1.) The drive that holds media is almost completely filled (about 4TBs) 2.) Apple did an update that prevents Mountain Lion Server from being able to be used anymore. I wanted to purchase NAS, but I don't think my company is interested in spending much money. So, the second best option would be just to do a full repurpose of the machine with bigger hard drives that will house everything necessary the company needs. Now, is this a smart idea? If so, what steps are necessary to properly setup the Mac Pro 3,1 to become a VPN/server again? Should I look through the guides that say how to install Sierra? Do I need a new video card? I need to layout a full plan to my employers to show them what is necessary and why it's necessary. Thanks in advance!
