Data Deletion in Receiver system for Multiple clients in TDMS 4.0 SP7

Dear Mates,

Can you please help on our below scenarios:

1. We have 3(100,200 & 300) clients in Receiver Systems, We are planning to migrate the data to 300 client from sender system.

    Does the step " Preparation of data deletion in the receiver system" will impact the data in Other Clients (100 & 200).

     I mean does it deletes the other clients data?

2. Currently We are doing a "Full Transfer of Client Specific data" from Sender(PRD300) to Receiver(QAT-300).

     IF we want to run migration again after 6 months, We select the "Time Based Reduction" for the 6 months period.

     Will this option copy only 6 months data and keep old data?

     or Time Based Reduction will delete all old data and copy only 6 months data into Receiver client?

Please Suggest.

Thanks you,

san's.
