I had a website that needed to be re-done, so I hosted a new dev site (not locally) with a temporary domain. The dev/new site was completed and I then moved the domain from the old site to the dev/new site. All seemed to work perfectly after the domain switch, except that the images/posts for the blog are taking forever to load and I could see in the browser when loading a post it was looking for the temporary domain and not the new domain. I checked the GUID column on the database and I see all the post_type and content etc. are still using the temporary domain URL. Will it be safe to use a plugin like Blue Velvet or an SQL querie to replace the temporary domain with the original domain without breaking the site?
I'm just a wee bit nervous to pull the trigger based on reading so many warnings to not touch the "GUID" column.
