Unless their failure was due to the burners plugging up or sooting or corrosion or such caused by bad gas (with dirt or water in it), would likely be coincidence.

Propane to natural gas conversion is possible on many units - your HVAC guy would have to check if conversion kits are available for your specific units - commonly a few hundred to $500 per unit to convert, so might not be worth converting hot water till it is time to replace the entire water heater.

However, generally if you have piped natural gas available at your house already, it will result in significant cost savings over time to use natural gas - your HVAC guys should be able to tell you, using the gas cost on your gas and propane bills, how much savings you could reap from the difference over a period of time. Sometimes the gas company will do this for you also - requires a conversion of the energy contained in the two gases (propane has nearly three times as much energy put unit volume as natural gas), plus figuring the average consumption times the difference in gas cost for the two gases (propane almost always being significantly more expensive per energy unit because of the more expensive delivery system).

Here is an article on that computation - not including the cost of conversion of course -
