Hello Subrat,
You can package all the deliveries by using package definitions under (Adminstration --> Package Management) and deploy from one environment to another.
If you want to update FROM and TO address for all the deliveries you can use update activity (if all the options are same) and run the query.
And the use the nmsDelivery for segmentation and the FROM and TO options are available under (delivery --> mailParameters --> Sender Address, Reply address).
Regards,
Venu
