How to raise the car to replace the serpentine belt tensioner?

Is it okay to raise the engine from the oil pan? If yes, please let me know how. i do not want to damage it. I am going to change the serpentine belt tensioner. To remove the long bolt going through it i will have to remove the bolts of the passenger engine mount and i will have to raise the engine. If not the long bolt of the tensioner will hit the frame and i will not be able to remove it.
