Yes, you can still collect up to the current cap - so when going from iron storage 7 to lvl 8 which costs 2900 iron, you can collect up to 3000 iron while it's upgrading (it takes 4 days, so easily done) and then send all your iron collectors to gather more iron, and leave the iron "on the dragon". As soon as the upgrade is done, collect all the iron from the dragons and send them out again.
