Moving a Magento store to another domain is actually very straight forward. Just copy the fileset across and import the database. Once that's done change the
base_url entries in the
SELECT * FROM `core_config_data` WHERE `path` LIKE '%base_url';
in PMA or similar and change the relevant entries to the new domain. Also worth checking a
cookie_domain is not set as this will cause issues if it's wrong:
SELECT * FROM `core_config_data` WHERE `path` LIKE '%cookie_domain';
and update or even remove the relevant entries.
The last thing you will need to do is update the database connection details in the file
From here you will want to clear all cache and sessions by deleting the contents of the
var/session/ folders, clear your browser cookies and that literally is all you need to do.
