When a troop upgrade finishes do existing troops get upgraded?

When you do a troop upgrade, for example to upgrade Riflemen from lvl 10 to lvl 11, will any existing Riflemen (which were recruited at lvl 10 and therefore the lvl 10 price) then be lvl 11 Riflemen once the upgrade completes?


Any existing troops will be upgraded to their new level after the upgrade finishes. While the upgrade is not finished yet, they will still be their previous level.
