I've been moving a few WordPress sites lately and I keep running into a minor issue, hopefully someone can lend some insight.
If I'm changing the path or domain, I create a dump file of the database, then open the file in Notepad++, run a search and replace for all instances of the old domain/path and replace it with the new. Then I import the dump file and re-save the permalinks. All the links and images display properly under the new path, but often the theme customization gets wiped out (i.e. the header image defaults, the navigation resets, etc)
I thought I was doing things by the book, but I must be missing something. Any ideas why these settings don't import properly?
