Same here, been a VDJ user since 2007 and still on the same DB with no issues whatsoever.
I know you shouldn’t have to but every single time I change anything in Engine I take a manual backup. I’ve read so many horror stories of this happening so whether I change something on Engine on the PC or on the player itself it’s backed up. I must have about a hundred of them now.
I know we shouldn’t have to do this but I have literally no confidence in Engine not to mess up at some point.
