Magento - How to Manually Change Base URL / Domain?

So it turns out the problem was that Apache didn't have write permissions to the WEBROOT/var directory, so Magento was using its cache from the system /tmp directory. (thanks for the tip, Fiasco Labs!)

In case someone gets here from Google, I'll reiterate the steps...

How to Manually Change Domain in Magento

1. Update your core_config_data table to edit the two records for web/unsecure/base_url and web/secure/base_url
2. Delete the contents of WEBROOT/var/cache
3. Update / edit any .htaccess domain redirects you may have added
4. Restart Apache
5. Make sure Apache has write permissions to WEBROOT/var
6. If you created a new DB, ensure that the WEBROOT/app/etc/local.xml is pointing to it.
7. If you're using Chrome, clear your browser cache! (Chrome caches 301s)

That's about it. Cheers.

Try to use FLUSHALL command on redis-cli, maybe you have a cached database.

It worked for me.
