Dha valley 5 and 8 marla transfer to bahria town

Hi everyone, i hope you guys have seen the ad from bahria town announcing the option of transferring the 5 & 8 marla plot to bahria karachi or bahria phase 8 islamabad.
What do you guys suggest? Should we do it or retain keeping in mind dha valley will definitely flourish after this transfer is completed as un necessary plots would be taken out.
