Existing Domain:
Export Your WordPress Posts – You can find the Export option under the Manage tab in your WordPress dashboard. You’ll want to save the file somewhere on your hard drive where you can find it a little later.
Download Your wp-content Folder – This step requires FTP access. You’ll want to copy over your wp-content folder on to your hard drive or place it somewhere you can find it later so that you can upload it to your new domain. This should grab all of your existing plugins, themes, uploads (pictures), etc. You’ll also want to download your favicon and Robots.txt file (if you have either).
Sub Domains and Sub Directories – This won’t apply to everyone, but if you’ve set up any sub domains or sub directories for your blog, you’ll want to grab the same files from them as well.
New Domain:
Install WordPress on the New Domain – This can be done manually or via Fantastico if you have CPanel.
Upload Your wp-content Folder – This requires FTP access to complete. Just override the existing wp-content folder from your fresh WordPress install.
Import All WordPress Posts – You can find the Import option under the Manage tab in your WordPress dashboard. When it asks for the import file, use the one that was exported and saved on your hard drive earlier.
Activate Your Theme & Plugins – Head into the Design and Plugins tabs and make sure you have the same theme and same plugins activated as the old domain name.
Update Your Settings to Match the Old Domain – Update all of your settings to match the old domain, including all of your plugin settings you just activated.
Inspect Your Theme – View your theme with your plugins activated and settings in place to ensure that everything looks like it matches the old site on the new domain. Test some of the functionality as well to ensure everything is working properly.
Upload and Run the Update URL’s Plugin – The Update URL’s WordPress plugin is brand new (just came out this month) WordPress plugin and the timing couldn’t have been more perfect for me! Once activated, simply enter your old domain URL and the new one. It will go through all of your old posts and update the domain part of the URL with the new one, and it only takes a matter of seconds. Note: I won’t update anchor text, only the domain in the URL.
Repeat Steps for Sub Domains and Sub Directories – Upload and setup your sub domains and sub directories using the same steps above.
