Moving a WordPress Site

For some historic reasons we originally installed our blog in a /blog/ subdirectory. There’s no longer a reason for this and as for now we have forwards in place that redirect all main domain traffic to the /blog/ directory.

Better yet would be if we could get rid of the /blog/ in the url.
One way would be to install a new wordpress site, export the current databank, import it in the new wordpress site and run update scripts in the new databank to update the URL’s.
But I wonder if moving all files from /blog/ to ‘/’ wouldn’t work in this case. (and run the same update scripts in the databank afterward.
Additional steps I need to do:
– get rid of the forward of ‘/’ to ‘/blog/’
– put redirects in place that redirect all traffic from the old to the new URL’s.
