On a few virtual systems I moved directly from 5.2 stock to 5.3
completely updated. There were no issues to speak of except that I ran
out of space in /var and had some trouble with the LVMs not resizing
properly. In short, I had to take the system down to single user mode
to unmount /var and resize the journal. Once that was complete, the
update went fine.

I did have a glitch some months ago moving from a 5.2 with some minor
patches to 5.3.  I lost the network connections to the Xen virtual
systems and found out that the default MAC address of the virtual
ethernet conflicted with the hardware address of the Linksys adapter.
Moving from 5.2 to 5.4 may hit the same issue.
