Since their discovery, upflows at the edges of active regions haveattracted a lot of interest, primarily as they could potentiallycontribute to the slow solar wind. One aspect that has not been studiedyet is how the long term evolution of active regions impacts theupflows. In this work, we analyze one active region that survives threesolar rotations. We track how the flows change with time. We use localand global modeling of the decaying active region to determine how theage of the active region will impact the extent of the open magneticfields, and then how some of the upflows could become outflows. Wefinish with a discussion of how these results, set in a broader context,can be further developed with the Solar Orbiter mission.
