Jdeveloper 11.1.1.6 upgrade integrated server to 10.3.6

NOTE: This may break some stuff so backup before you proceed so you have been warned

Prerequisites:
Install JDev 11.1.1.6
Run integrated weblogic.


Now install just weblogic 10.3.6 I used the generic installer.
java  -jar -D64 -Xmx1024M wls1036_generic.jar

Next > Select Create new MiddlewareHome and enter a value > Next > Typical > Next
Now select your JDK and click Next * 3

Run QuickStart

Click Next
Select 9.0 or Higher
Click Next

Find your integrated domain  [usually under C:\Users\[username]\AppData\Roaming\JDeveloper\system11.1.1.6.38.62.29\DefaultDomain]

NOTE: On windows I had to make this folder ! read only but this is not recommended. If you don't want to do this Install your integrated server in a different location

Click Next.


Once the Installer has finished backup setDomainEnv.cmd then copy setDomainEnv.cmd.back to setDomainEnv.cmd and edit the line:
set WL_HOME=... and make it set WL_HOME=C:\Dev\Oracle\Weblogic_10.3.6\wlserver_10.3

The location for these files is:
C:\Users\[user]\AppData\Roaming\JDeveloper\system11.1.1.6.38.62.29\DefaultDomain\bin
