Ubuntu upgrades

[Chris]

Question from a new Ubuntu user. Previously when running
Mandrake/Mandriva I would upgrade to what would be considered major
upgrades such as 2009 to 2010 and so forth. I see that Ubuntu 14.10 is
soon to be released, is this then a major update from 14.04? Next
question then is if so what is the easiest way to do the upgrade without
destroying my current 14.04 system?

Thanks
Chris
