Hello Preetham,
DTP is Data Transfer Process,  to transfer data within BI from a persistent object to another object in accordance with certain transformations and filters. In this respect, it replaces the data mart interface and the InfoPackage. As of SAP NetWeaver 2004s, the InfoPackage only loads data to the entry layer of BI (PSA).
Simply, DTP --> do the Data Transfer with in the BI (from PSA or InfoProvider to InfoProvider) based on the rules defined in Transformation.
Refer the document at

In upgradation project, you can able to maintain both object versions 3.x and also 7.0.
So DTP is not Mandatory for your objects,
If you want to follow the 3.x features only, you can go but you will not get the 7.0 features like error stack and other.
