Table 1 shows that the target Oracle database environment contains newer releases of both hardware
and software compared to the source environment. The target system consists of not only the latest
hardware including servers, storage systems, and SAN switches, but also newer operating system
releases on the database servers. The Oracle database version remains unchanged on the target
system. It is beyond the scope of this paper to discuss the Oracle database upgrade process. You can
find Oracle database upgrade best practices in Oracle documentation.

Migration Options
There are many different ways to migrate the Oracle database described in the above reference
configuration. Among them, some commonly used technologies are:
Oracle Data Pump Export and Import utility is a feature of the Oracle database that enables data
and metadata movement between Oracle databases. This method involves the exporting of the
source database into export dump files, presenting the dump files to the target database, and then
importing them into the target database. This method can be slow for large systems and can incur
an extended downtime during the migration process.
Oracle Transportable Tablespace is an Oracle database feature to copy a set of tablespaces from
one database to another. This method involves exporting the metadata, transporting the datafiles
from the source database to the target database, and then importing the datafiles to the target
