Hello,
is there a Migration Wizzard or a little Tool to Mirgate a DBExpress Project in Delphi 2009 to UniDac?
Thanks for your answers...

Looking at the migration wizard, I only see options for:

BDE
IBX
ADO
Specific DACs (ODAC, SDAC, MyDAC, IBDAC)

Regards, Paul.

I´ve seen that before, but is there anyone who has done a migration from DBExpress to UniDac?
Has anyone a Migration-Tool or something other?

Hello

DAC uses two-level data model: Connection -> DataSet
dbExpress uses three-level data model: Connection -> ServerDataSet -> ClientDataSet

We created migration wizard for BDE because BDE and DAC have two-level data models. Unfortunately, Three-level data model, that is used in dbExpress, cannot be converted to two-level data model automatically.
