We have an ePO server at work, which is 5.1, and the team in charge are too worried about doing an upgrade to 5.10. Is it really that scary to do an upgrade? Surely it is easier than building a new server, installing and configuring it, restoring the data (we use AV and DE), and migrating the clients across?
Or is it really fraught with perilous dangers?
Given we have no documentation on the existing setup, what would people recommend? Upgrade, or build new and abandon the current ship (which is running without issues by the way, just hasn't been maintained).
