I move alot of sites from our development server to a live environment every week, I usually leave the dev site up for a few weeks just incase I need to reference the dev when making any changes to the live site during the first week or so.
I also do a migration on the DB for all the dev url into the new live url.
The move today, I had to kill off the dev site as soon as I moved the live site. and I noticed that all my images has disappeared. After some testing a I found out that the beaver builder css file was still referencing the dev site. it was not until I re saved the page that the css rebuilt its self and I got my images back. I had re save every page to get all pages to show the images.
my question is there a way when I move the site that I can have the images url update and have the system rebuild the css without resaving every page?
