Path changes with move to VPS
At least a couple times a month, I copy our live site over to the dev version, which means different paths. I just make sure I:

delete the templates_c directory and let it recreate itself

change the civicrm.settings.php file

check the directories page in CiviCRM: administer > system settings > directories

check the resource URLs page in CiviCRM: administer > system settings > resource URLs

clear caches and update paths: administer > system settings > cleanup caches and update paths

Running through all these steps always fixes any changes in my installation directory.
