I've had a bug once or twice, so 10% maybe?? We have very simple installs, no clusters more than 2 servers, no user bases more than a 1000, and nothing more sophisticated added other than CCX or CUACA. We upgrade internally to the latest version first, but outside of a quick release notes reading and verification of compatibility it's not a lot of prep, maybe 30 minutes to an hour. Albeit, I usually am following along in the communities for the betas and various partner and CCP webcasts so I'm aware of any big changes/caveats ahead of time (like the end of support phone models, etc)

When you or your customers have a UCM or IMP upgrade fail, what percentage of failures are due to a bug vs something in the environment (user error, db updates, etc)? % bug: % not a bug: Yes it’s a very subjective question but that’s ok, use your judgement. 2. When an upgrade goes smoothly with no issues, how much time do you put into the planning and preparation for the upgrade (not the execution)?
