converting from SOAPUI driven test to DT driven test

we have a few services written with DT. and now we want to engage test to take them over and maintain them.

today we use one spreadsheet, where some columns below to the service (data to send in response to message)

and some columns below to SoapUI (data to send, expected response.. etc)

I think we can do the same with DT test. and I KNOW I can code it up..

just wondering if there are any docs on migration or best practices when coming from other tools..
