nope, unfortunately not.  There were manual steps which needed to be 
handled at various .dot release points, so it wasn't possible to 
automate this fully.  If I understand it correctly, this should be much 
better in the up-coming version of IXP Manager, which has migrated away 
from doctrine to eloquent for the ORM layer.

This means that for 5.x, you need to go through each of 5.1 -> 5.2 -> 
5.3 -> etc in turn.

There are situations where you could skip individual dot versions, but 
we don't recommend it.  It's safer to go through the lot.
