Migration from Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 Server

Question

I am working on migrating Oracle 9i 32 bit to Oracle 10G 64 bit on Windows 2003 from Old server to new server. We have db around 500 GB and 3 schemas. I installed Oracle 10G on new server, created tablespaces, schema's blah blah and now doing export and import at schema level from old server to new server.
Import is taking more than 4 to 5 hours on new server. My manager is saying, window time is bit longer and he wants me to try possiblities to make this process faster. Can some one help me on this, to use the best possible method to complete this process faster?
Will below step work, if I try?
If I install, oracle 9i and 10g both on new server in different home directories and take the hot backup from old machine and restore on new machine in 9i home directory and use the upgrade configuration assistant from 10g and do the upgrade? Pls advice.
Thanks in advance,
Hari babu

Answer 1

It looks good.
I have one question in below steps:
To migrate an Oracle9i or older database to an Oracle Database 10g Release 1 (10.1) database for 64-bit Windows:
1 Perform steps 1 - 11 in "Migrating an Oracle Database 10g Release 1 (10.1) Database".
2 Shut down the database on the 64-bit computer:
SQL> SHUTDOWN IMMEDIATE;
3 Start the database migration:
SQL> STARTUP MIGRATE;
4 Migrate the database as described in Chapter 3, "Upgrading a Database to the New Oracle Database 10g Release" in Oracle Database Upgrade Guide.
In step 4, it says, migrate database as described in chapter 3. In chapter 3, it says, to do the upgrade the process using dbca or manually. Pls confirm whether do the upgrade process after issuing startup migrate or not.
Thanks in advance.
