I'm trying to upgrade weblogic 10.3 to 12.1.1 but I'm receiving the following error, could someone have an idea about this? I am not very clear about the error.
I tried to upgrade first to 10.3.6 and I receive the same error
Direct upgrade from 10.x to 12c is not possible. You have to first upgrade to 10.3.x and then from 10.3.x to 12c. See this documentation for details. The 12.1.1 version is out of date, you should consider upgrading to 12.2.1.4 or 14.1.1 instead.
