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.
