    Upgrade path question: We have a business critical web-application, using a lot of mod_plsql, which runs on iAS (on RedHat 4) which in turn connects to DB (on RedHat 6).


      We have started planning an upgrade path, wishing to upgrade the RDBMS to 12.2.x.

      But since the iAS is 10g on RHEL 4, we also need to upgrade this to iAS 12.1 (12.2 does not have mod_plsql, right ?) on RHEL 6 or 7.

      But we propably can't upgrade it all at the same time, so maybe the following sequence could work:

      1. upgrade the DB first ( à 12.2.x) and let it run a short while against iAS, although it is not certified.
      2. upgrade Linux (RHEL 4 à RHEL 7), although this iAS/Linux is not certified.
      3. upgrade iAS ( à 12.1), hoping the iAS12.1 will work fine against DB 12.2.

      What do you say ?
