Its no problem, my only word of caution is you have a virtually maintenance free exterior that now will require maintenance. Has the brick had any kind of silicone sealer applied to it in the last 5 years? if so that will be a problem.
Does it have deep mortar joints? if so a roller may not get into them and so it may need to be sprayed.
Clean the brick and power wash, apply SW Loxon primer, if the brick is really absorbent then I would consider two coats of Loxon primer.
Top coat with two coats of good quality exterior satin paint such as SW Duration.
Yes that is four coats of paint, but it is your home. Get a good foundation of primer on it. Use the best quality products so you are not repainting it every 5 years, anything less will be false economy.
