Since the untimely loss of our Network Administrator, we have yet to do a version upgrade to Tessitura. We're currently on version 14.1.3 and want to upgrade to the latest version of 15 on our test server at the end of this month. This will be the first time I've ever done an upgrade myself, so I admit it to be more than a little daunting. I've never seen or used TIM and have no idea how long the upgrade will even take.
Can anyone point me in the direction of some helpful documentation of this process for a newbie? Anything I should be aware of? Any considerations to keep in mind so I don't find something critical to the process on the day I try to implement the upgrade? I'd greatly appreciate any advice.
Thanks in advance as always, Tessiturians.
