How to move to RedHat Linux and OBIEE 12c from OBIEE 11.1.1.9 on Windows 2008 R2 servers

I need to present a detailed proof of concept.

Gianni Ceresa

Did you read the doc?

There is quite a lot written about the 11g to 12c upgrade...

The change of OS isn't really going to be an issue (transparent for the RPD and catalog content in the end)

+1 to Gianni - the OS is a non-issue in the purest sense of the migration.

The migration takes across 3 entities:

1.) The RPD. Here the platform change makes no difference since it is inherently a proprietary binary file but the new deployment processes are all using it in its MDS XML for so that means....pure text files.

2.) The web catalog. It's a file system with some bells & whistles attached. The bells&whistles being the application properties and security ACL applied through the .atr files. And those themselves are nothing but HEX-readable text files again.

3.) The security. and more specifically only the translation of groups/users into Application Roles and Application Policies. All other security like security realm setups, SSO integration etc etc are not transferred and re-done anyways on the migration target environment. So just the roles/policies and mappings get transferred and this anyways is something internal to the WebLogic platformand done through its (WLS) own mechanisms which means that platform jumps are no hurdle at all.

In the "worst" case if you feel you can't or don't want to use Oracle's migration approach you can do all the migration yourself as well with the command line utilities which exist since a long time. Oracle didn't re-invent the wheel for this migration - it just nicely packages the whole thing to make life easier for you. That said I just did a full manual migration and it works like a charm with zero disadvantage to the "official one" except for "I had to do it".

Can you please share the command line utilities you used?

Gianni Ceresa

Why do you look directly for a workaround-do-it-yourself-by-hand way?

Use the standard process, read the doc and follow the steps of the doc.

If it doesn't work, and after analysing issues you can do thing by command line.

The command line tools are the ones included in OBIEE: runcat.sh , datamodel.sh

Nothing special.

But first follow the default process.

Which one of those did you get to so that you immediately ask for commands?

Have you even done a migration yet? Gianni obviously went ahead and mentioned the commands but that doesn't invalidate my point: Have you DONE a migration yet? Have you run into issues? If no. Do it.
