DTW of transactions

Hi Experts,

One of my clients want to reimplement SAP Business one 9.0, with new settings. They are currently running in 2007B. They want all the existing documents (Open and closed)  in the old database to be in the new DB. Please advise how can I acheive this.

I am thinking about importing the old transactions using DTW. Will this work out?

Thanks,

Anandh.
