I believe you have to first upgrade to 5.1.x before you can go to 5.3. Be
sure you back up your config and have a copy of 4.4 around so that you can
downgrade easily. A lot has changed since 4.4 and 5.x. For instance, you
can't have two default gateways (or two routes to the same networks on two
interfaces). This screwed us when we upgraded a while back and had to get
RIP working with the PIX to learn all of the inside routes we have.

upgrading to 5.3 without stepping up incrementally and just going directly
from 4.4 to 5.3. I don't see anywhere in the Cisco documentation where they
advise against this, but I seem to remember several threads here advising to
go up one version at a time. Any thoughts??
