what happens if i install 12c enterprise edition in a system where 11.2.0.2.0 standard edition is already present in a normal desktop of windows environment
the database 11.2.0.2.0 will get updated to 12c ?
Do we need to un-install 11g R2 ?
Is there any config changes need to be done before installing 12c to upgrade the database from 11g R2 ?
Please drop your comments, Thanks in advance.
