If you are going to break the cans down into meals, you'll need to vacuum seal the separate meals you make.
A Zip-lock (most of the time - 99.9999%) will leak a bit over time, and you'll draw moisture into the meal.
Not an issue if you plan on eating every one of them in 2-3 days, but it will be if you have leftovers.
However, I think the posts above are spot-on, unless you get a killer deal on the cans, the cost to repackage isn't going to save you much...if any.
