The rigger who last packed your gear can mail you a new data card with all the info about serial numbers, etc, and the latest repack only, on it, so you'll be able to prove you're in date. You'll be missing documentation of any repairs that may have been done, but that's your only disadvantage, really. If you aren't planning to jump it before its next repack is due, you don't even need to bother with that - the next rigger will give you a new data card when they pack it.
