From the forums it seems most are moving from 7.x straight to 8. At the request of a number of our clients we are deferring upgrades to 8 (the GUI is just different enough that retraining for end users is called for) and instead planning on upgrading from 7.1.3+P1 to 7.2.1.

Would be nice to hear from others who have already upgraded to 7.2.1 as to their experience...
