Upgrade from 1.7.8 !!
hey,
I'am trying to upgrade deom tikiv1.7.8 to an higher version but i'am not able to take a backup of mysql database.
even if i use "mysqldump" or "phpAdmin" command in mysql, my systems hanging or crashing and once in a while displays an error that the command is invalid.
Moreover once even if i take a back up, how possibly could i retrieve all the previous data into new mysql.
regards,
sunny
