I wish to install fresh magento 18.104.22.168 using the same database of magento 22.214.171.124 During installation process when I give the same database name as of magento 126.96.36.199 It shows error as"Database connection error". Is it possible to use the same old database or should I create a new one?
Answer Found. The method which I followed was correct.We can give the old database name & its details (username and password) during fresh installation to use the old database in new magento.Database error occured. But once I restarted the xampp server the error disappeared.It was that simple and that easy.
no you are wrong, you must never install new magento on top of your old database, in fact you wont be able to install it, or you will break it.
but instead you have to in magento 188.8.131.52 change details in local.xml to connect to your old database and open your index page to trigger the updates...
