I have a product datafeed in which the categories have been updated. In one instance, two categories (from the old datafeed) have been merged into one single category. Each of these two (old) categories had a seperate page. Now that they are merged, I need to redirect each old category page to that one single one.

My question is: will using a 301 redirect from each of those two pages, to that one new single page cause any problems? Specifically, do you think Google will penalize this in any way?

Thanks
