I am new in magento, i need to know how to upgrade magento 126.96.36.199 to 188.8.131.52
(I use ubuntu 15.04, what are the necessary commands ? )
Thanks for help :)
maintenance.flagfile inside 184.108.40.206 code folder to put website offline.
maintenance.flag(but you should have backup somewhere) and place all folders and files from the 220.127.116.11.
adminhtml/default/default/(18.104.22.168) to adminhtml/default/default/ (22.214.171.124).
app/etc/local.xml.Edit database details their.put your database username and password and database name.
maintenance.flagfile and check the site in the browser. it is done.
