Complicated questions for BW re-implementation

Active Participant

Dear Expert,

I am re-implementing BW 7.40. I will try to keep the old BW 7.0 system lives for a short period of time when my new BW system goes live.

Here are my questions:

(1) Is anyway I can avoid running the stock initialization process again in ECC system for the new BW system since I am afraid It will break the old BW system?

(2) Is anyway I can copy data from the old BW system to the new BW system?  I didn't delete data from PSA for all datasources in my old BW system. For example, 2LIS_03_BX, 2LIS_03_BF, and 2LIS_03_UM.  However, I have started the archiving process in my ECC system so some data in ECC has been archived even those archive data is already in the old BW system.

(3) If I didn't run the initialization load in the new BW system, how can I setup the connection between the ECC and BW system for the stock delta update?

You can look the note 886102 for some tips

It looks like you want to do something as scenario B1.
