In my case, I developed a DTS system contains 40 DTS packages, If I use the way that you said above it will take me a lot of time and effort.

I write a simple program in VB to transfer DTS from one database to another, it works well. But when I save DTS to storage files and after that, I import DTS in to SQL Server and all DTS's layout has changed.

Any one here know which way to import DTS and their layout are not changed?

Thank you in advance.
