I'm at a RHEL shop so the concept of an in-place upgrade is pretty foreign, and I haven't actually gotten Red Hat's in-place upgrade script to work from 6 to 7 in staging. I've been mucking about with Ubuntu lately and I'm just curious for those who have made the leap from 12.04 to 14.04, or even 10.04 to 12.04 first, what your success rate has been like where your at. How many legacy systems have you upgraded? From what version? And what are some of the pitfalls you've experienced?
