Mirror Replication Agent for Oracle migration process to support Oracle 9i to Oracle 10g migration is similar to migrating from Mirror Replication Agent for Oracle 12.6 to Mirror Replication Agent for Oracle 15.0.
You need to verify that the Mirror Replication Agent is quiesced prior
to migrating from Oracle 9i to Oracle 10g. That is, the replication environment
must have completed processing of all transactions prior to migrating
because the Mirror Replication Agent moves the truncation point to the end of
the log during Oracle 9i to Oracle 10g migration.
To migrate from Oracle 9i to Oracle 10g
Follow the steps that Oracle provides in their documentation for upgrading from Oracle 9i to Oracle 10g.
After migrating Oracle, you must re-start the Mirror Replication Agent and issue the ra_migrate command.
As with the 12.6 to 15.0 migration, you may have to re-configure the Mirror Replication Agent for Oracle instance to read archive logs depending on the configuration in Oracle, which may change following Oracle migration.
If you are migrating from both Mirror Replication Agent for Oracle 12.6
to Mirror Replication Agent for Oracle 15.0, and from Oracle 9i to Oracle 10g,
you need to migrate only once.
