Ripple Edit works well for me: all track automation, BUS automation, clips and markers are affected and it's quick and simple!

(Ok, I've had a few instances were a single clip wasn't really affected, but it might've been I forgot to split it.)
Ripple Edit it's what I've been waiting for for ages (
here are some 8 year old Sonar 8.5.2 posts about it)! Restructuring projects with a lot of automation, including bus automation, is now so much easier. Thanks Bakers!
Now if we only could have one of those arranger tracks as well... ;)
