Hello everyone,
We've been using an older version of PDI on a CentOS server to execute jobs and the new version 5.5 + version 6 had some useful plugins so we upgraded.
Everything was going fine, until I attempted to upgrade the server's version on PDI.
After uploading and replacing the contents of
/app/pentaho/design-tools/data-integration
with the new version we got this message.
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/pentaho/commons/launcher/Launcher : Unsupported major.minor version 51.0

My researching kept pointing to java compatibility so We tried upgrading the java on the box from
[dmi@sc-dmipdi1 ~]$ java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
to official oracle java 1.7
[dmi@sc-dmipdi1 ~]$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
and then out of desperation even tried to downgrade it back to 1.6
[dmi@sc-dmipdi1 ~]$ java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
Whiel I've worked indirectly with PDI for 2 years I'm very new to this server side setup.
I wondered if there was a settings file that the old PDI had, installed before my time. So I compared as many as I could but didnt see anything relevant to our setup that needed to transfer.
we did save the old PDI at @
/app/pentaho/design-tools/data-integration-old/
and the kitchen.sh still works there with older scripts.
I am unsure of where to turn next, so was hoping someone here may have an answer or could point me int he right direction.
Please let me know if any additional information from my side would be helpful.
Thank you for your time and attention
Edit 1:
Note I downloaded the PDI instance for version 6.0 directly from: http://community.pentaho.com/projects/data-integration/
