migration of master data from 3x to 7.3

Hi All,

I am migrating my master data from 3x to 7.3.I am aware of the new wizard in the 7.3 system as stated in the below link

BW 7.3 : Data Flow Migration Tool

But i have few doubts for the same.In the above link they have given a recovery process.Do i need to do these steps if i want to revert back to 3X flow or wht?

Also when i try to migrate my text data flow i get a pop up saying Infoarea "Nodes not connected".Do i need to specify the infoarea.Wht happens if i dont give it.

Is there any additional steps i need to concentrate.When we use the new wizard everything captures in a project name does this gets migrated or individual objects.

Kindly help.

Regards

Kumar
