thanks Wes. 

i think we'll start DMA sooner rather than later.

MANY variables: 
how many times upgraded 
how many interim versions were run 
what native or 3rd party tools attempted to modify the database 
who attempted directly editing the database 
how many dbl/iis problems have been encountered? Unfortunately transactions were not strictly enforced so when problems occured there were partial commits to the database 
Is enterprise LDAP integration used? This is probably the largest contributor to errors. When objects move in the enterprise there is no change notification to CM (unity tried but CN from AD appears rather unreliable) so CM ends up with numerous broken pointers in the database. 

The other systemic problem is that 4.x enforced business rules via DBL rather than directly in the database. Think of having a guard in front of your storage room, but your storage room has no shelves. Users must verify with the guard but once inside they have free reign and very little structure.

well, this doesn't sound promising. what kind of garbage exists in 4.x databases?

imho. run DMA. it it works for you then that is the shortest path. 
if DMA reports errors that you cannot easily repair then stare and compare. 

dma has improved significantly and even better with 7.1. however, there is so much garbage possible in 4.x databases that the migration tool simply cannot always be accurate.
