This is my first Multisite that I built to help me manage the websites of my small clients. I have three static client sites with a couple pages each that I built on separate WordPress installs plus my personal food blog. When I decided to merge them, I exported the content from each site using the WordPress import/export tools and recreated the settings, widgets and everything else manually within multisite. I figured that would be easier than merging databases and what not.
After I finished mapping the domains, I noticed that the URLs were mapped to the right pages on the new multisite host but the image links were still tied to the subdomain in multisite. So the image links for reggieandjimsbbq.com were on bbq.bfh.wpengine .com.
I changed the domain under the edit screen on the all sites network page for one site, but then I noticed I couldn't go from site to site on my network. I have to login like they're separate sites and for me that defeats the convenience of the multisite, so I'm pretty sure I did something wrong.
Also this post:
leads me to believe that the domain mapping plugin was supposed to change the site domains in the database automatically but it didn't?
I've never done this before so I'm not sure what the end result is supposed to look like.
