I have hundreds of identical joomla installations on same server. For two years, I have been updating and maintaining them seperately which makes me too tired and causes too much time and energy loss. Because I do not have time I only want to get suggestions if you have tried something like my intention:
I want to upload all joomla core files/folders to one directory on the server. Then all remaining sites will have only configuration.php and images folder.
With this situation, I will be able to centralize the maintenance.
Is this possible? If so what are the drawbacks?
