How long does vacuumed sealed cooked BBQ pork roast last in a refrigerator?

I cooked two vacuum sealed 8 pounds each, pork Boston butt roasts after 5 years of being solidly frozen, tasted great and nobody got sick or died. I'm baking the other two today, 1 year later. If i croak, please tell every one the time limit is only 5 years. lol

will let you all know how the 6 year frozen roasts do.
