When you replace the heater, which is what I think you should do given the age of your existing tank vs its warranty, also buy two replacement thermocouples and tape them to the tank. Thermocouples are the weak link in the system, they're easy to replace, and they cost less than ten bucks. Also get the part number for a replacement anode and write that, and the appropriate date to replace the anode, in Sharpie on the side of the tank. Consider buying the anode as a ready-service spare too.
I also have not seen a compelling reason to go with a tankless system except possibly in a second home for a large family that has only occasional use for large quantities of hot water. Big outlay up front, long slow cost savings, longer wait for first burst of hot water...no thanks.
