"The conditions there (South Africa) are completely different to what we are facing here in England. We can take a lot of confidence, but we need to start fresh again in the World Cup," she added.
This World Cup will be the eleventh edition and the third to be held in England (after the 1973 and 1993 tournaments). Eight teams qualified to participate in the tournament.
The 34-year-old batswoman also said the bowlers have to pitch in the right areas because the conditions here might play a crucial role.
"If you are able to bowl in the right areas, there should be a bit of movement off the wicket, and the weather might play a big role as well, if you are able to adapt," Mithali said.
Indian eves finished seventh in the previous edition of the World Cup, but this time, Mithali-led India are eyeing the title with a much improved performance.
"The World Cup is a big stage, and that's four years of preparation. We're looking forward to it, it's going to be my fourth World Cup, so I'm looking forward to some good games," Mithali said.
