I am working on an upgrade on to


My current middleware home is /u01/app/oracle/product/Middleware.


Do I need to change my middleware home to something like /u01/app/oracle/product/Middleware_12c or will the currnet( /u01/app/oracle/product/Middleware) middleware be upgraded.

    If I choose a new middleware home  /u01/app/oracle/product/Middleware_12c.Then instance base directory should be  /u01/app/oracle/product/gc_inst.


    But /u01/app/oracle/product/gc_inst already exists for my OMS.

    When I upgrade from to, then later to

    each time I had to create a new middeleware home and base directory..


    I ended up with these    /Middleware and /gc_inst   /Middleware12102   and /Middleware12102/oms  (I put the base directory in the middleware folder and named it OMS)  /Middleware12103   and /Middleware12103/oms

    11g to is out of place upgrade which mean you will get a new middle-ware home.  Starting the gc_inct is outside the middle ware home.

    Suggestion -

    So in 11g if you have -/u01/app/oracle/product/Middleware then i suggest you provide this during upgrade for new middleware home- /u01/app/oracle/product/12c/Middleware and inst home will be -/u01/app/oracle/product/12c/gc_inst
