migration a text index from oracle 10.2 to 11.2

Hello,

I'm trying to migrate a 10g oracle database to 11.2 on another SUSE Linux 64Bit box.

The application is using oracle text and I have a text index like:

CREATE INDEX JOURNAL.IDX_J_EREIGNIS_TEXT ON JOURNAL.J_EREIGNIS (J_MELDUNG)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('SYNC(ON COMMIT) datastore ereignis_meldung_pref lexer german_lexer')
NOPARALLEL;

Now my Question:

What's the best way to detect all needed informations for a new text index recreating on the 11.2 SUSE Linux box
like lexer, preferences, wordlist and stoplist?

Thank you very much for all hints.

best regards

Stefan
