There is an extensive procedure discussed in the Netview 5.1 release notes
and manual about migrating.  However I've been told that it is better to do
a brand new install of NV5.1.  Recall that you can save your trapd.conf
from your old version and copy it over the new trapd.conf or do cut 'n
pastes of the differences.
