Data Conversion Utilities for v4 Upgrade

We're planning for our upgrade to version 4 of Vantage and have identified 3
separate areas we need custom programming to help us with data conversion.
We are currently using v3 with many workarounds to support our multiple
production facilities.

My question to all those who have already upgraded:

Did you need any custom programming to support your upgrade?
Could you give me an idea of what issues you had/have?

I feel we've been very thorough, but I'm also concerned about missing
something and getting bit in the end. Any thoughts or feedback will be
greatly appreciated.
