Yes, but not anywhere!
Traditional etiquette requires the bride to move her engagement ring to her other hand (if necessary) while walking down the aisle. This must be done if the wedding band is to be placed onto the finger currently "taken" by the engagement ring. Moving the engagement ring to the other hand allows for the hand to be "free" and for the wedding band to take its entire and full meaning on its very own special day: the wedding day.
Let us observe how this rule applies in America, in Germany, and in Austria.
