Migrate Google+ photos to Google Photos and free up Data Quota I see my old Photos that were uploaded to google+ in the new photos app.  I have it set for the new free high resolution, but I still see google+ photos taking up 7 gbs when I go to drive and check my quota.
Can I delete the photos from google+ or should I try something else first?
I would prefer not to lose my old photos. I would think they would be moved to the new free storage because they are all smaller than the 16MP limit for the high resolution now.
Google hasn't announced anything about moving these. While it's possible, if not likely, that they may do so at some point, your only sure-fire solution would be to download all your photos, delete them from Google Photos, and then re-upload them under the new setting.
