It is not possible to convert a rich photo, or pattern like this fully into vector format. Well, you COULD theoretically, but the file size would not benefit you, and it wouldn't make it easier to color shift.
Now, you could make an approximation. If that's what you are looking for, someone here might be able to help you.
I guess the main question is,
what is the purpose of your need for a transition from raster to vector?
