We've had quite a few customers do it. Most without any help from our tech team. We've had a few decide to pay us to do it. I would say that if you can follow the instructions carefully - don't try to wing it - you'll be fine. We've only had a couple that truly needed a technician for problems around the switchover. One was just to do some calibrations in service mode.
I would recommend that you replace cap tops before doing this if you haven't done that in the last 6 months. Also perform a thorough manual cleaning before doing it.
Good Luck.
