WD does successfully import both VWS and WU. 1037Ob2.
The key is to import monthly, using CSVed, to create seperate monthly files. WD only imports the monthly, long format.
The bad news...my 2009 VWS dbase.csv has not been updating properly. After the dbase file reaches capacity, it should write to the 2009 file. That hasn't been happening since Mar09, after doing a VWS beta upgrade earlier in the year...probably the major beta upgrade that did some serious changes. I highly advise you to check your 09 master db. My 09db is 1Jan-16Mar. The dbase file is 21May to current.
Thankful WU has the dailies. Cut and paste into monthlies to fill the blank 2 months.
I'm just happy to make the transition.
