How do I change the CiviCRM Database name
This is what works for me but not sure if it is necessary based on the following http://wiki.civicrm.org/confluence/display/CRMDOC/Moving+an+Existing+Installation+to+a+New+Server+or+Location :


Edit civicrm.settings.php with new database info
Delete all template files in templates_c/
Make sure there are no references to civicrm database in drupal setttings.php
Clear database caches and session tables
