About 32-bit Oracle Databases to 64-bit Oracle Database Conversions

32-bit Oracle Databases are automatically converted to 64-bit.

If you are installing 64-bit Oracle Database software, and your existing Oracle Database is a 32-bit Oracle Database installation, then your existing Oracle Database is automatically converted to 64-bit during the upgrade to the new Oracle Database release.
