I am an WordPress user absolutely no design or programming knowledge. What would the best option be in the long term. I have been using one theme from one designer for seven or eight years. The theme is being retired with no up dates for the last 4 years. I have 5 sites and around 1500 Post with videos in the featured embed code custom field created by the theme. I now have to move the video shortcode or embed code out of each post and put it on the top of the post. It would have been alot easier if I could have just changed the theme without going through the long process.
