We are using Oracle 8i in our production and we have a plan to upgrade it to Oracle 10g.
Lets say we have upgraded our production database to Oracle 10G and it is working fine for 1 day. After a day, lets say we found an show stopper issue which cannot be fixed in the near future.
Now in the case, we need to replicate all the data changes done in the Oracle 10G database to our old Oracle 8i database.
kindly let me know, how to acheive this.
Thanks and regards,
