Moving Wordpress
Saturday, January 2nd, 2010Move Wordpress from a subdirectory to website root
This example should work for any Wordpress deployment, this article describes how to move Wordpress on IIS 7 using ASP.Net
Benefits
- Move Wordpress
- Preserve old links and permalinks
- Preserve old images and uploads in posts and pages
- Notify crawls of change with HTTP Response 301 Moved Permanently
This configuration will allow you to move Wordpress to a different directory within your site and maintain you old links, permalinks, images, and uploads. All of the content will move with Wordpress, this will just setup redirects to the new location. Each time an old link is used a HTTP Response 301 will be issued, this will help update search engines and backlinks. Custom HTTP Response 404 handling will be used to issue the HTTP Response 301.
Steps
- Setup HTTP Response 301 Moved Permanently using ASP.Net (default.aspx)
- Modify HTTP Response 404 Not Found handling using IIS 7 (web.config)
- Modify rewrite rule to exclude old path using IIS 7 (web.config)
- Update Wordpress settings in database using MySQL
- Update Wordpress posts in database using MySQL
HTTP Response 301 Moved Permanently using ASP.Net

Sub Page_Load(sender As Object, e As System.EventArgs)
Dim sUrl As System.String = HttpContext.Current.Request.RawUrl
Dim bChange As System.Boolean
bChange = FalseIf sUrl.IndexOf(“?404;”) > 0 Then
sUrl = sUrl.SubString(sUrl.IndexOf(“?404;”) + 5)
sUrl = sUrl.SubString(sUrl.IndexOf(“//”) + 2)
sUrl = sUrl.SubString(sUrl.IndexOf(“/”) + 1)
Else
sUrl = “”
End IfIf sUrl.IndexOf(“blog/”) = 0 Then
sUrl = sUrl.SubString(5)
End IfResponse.Status = “301 Moved Permanently”
Response.AddHeader(“Location”, “http://www.domain.com/” & sUrl)End Sub
</script>

Food for thought, (at least the bits I could make out easily). I am afflicted with color blindness (deuteranopia in my case). I use Chrome browser (no idea if that makes a difference), and much of this webpage is a bit of a strain on my eyes. I don’t wish to whinge, and I know it is my problem really, nevertheless it would be great if you would consider color blind surfers whilst carrying out the next webpage redesign.
