old wallet question

I have an old wallet of rdd that is out of sync, I noticed there is a new version out, my question is if I let it sync first then update to the new wallet will I be safe to use my rdd or should I update before sync?

Wallet and blockchain data are compatible. However we changed the location of index data. I would suggest to backup your wallet.dat and use v2. You might find v2 a bit faster to sync.
