How do you flip a volume on the fly? I thought you had to do the "snapshot > make new volume > reattach" route

Read the limitations very carefully, http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/considera... In particular if it was attached before Nov. 1, 2016 you need to do a one time stop and start of the instance or detach/reattach the volume and there are limits on instance types supported (but the definition of "current generation" is broader than you might assume at first).
This is quite an awesome enhancement, we were able to transparently convert a bunch of 15TB volumes from gp2 to st1 without downtime or impact to the app, and save a bunch of money.
