They have explained the point conversion in the document released I guess. If you hold a Citi Rewards card, 1 point = 0.35p whereas for Axis Rewards, 1 point= 0.25p. So if you have 100 points in your Citi card account, you will get 140 points in your Axis card account post migration. So, 1 Citi RP = 1.75 Axis ER.
