Should check out what your current plan covers and what's the sum insured first, as well as surrender value/value of units accumulated if any. Then you may engage a few agents from different companies to compare

Misc things to factor in: Whether you have MRTA/MLTA to cover house loan, EPF also can withdraw if you hit certain health conditions, number of dependents (that's people that depend solely on your salary, people that will literally lose a roof over their heads and no rice to eat if something happens to you)
