The summary of operations
The summary screen lists the options you have chosen and is the last time when you can change your mind.
Carefully review the options, and when you are happy you need to click on “Finish” to begin the actual migration
which might take a little while. Please note that the progress window is not shown here. After the migration
completed, you are shown the results screen which again lists source and destination databases, any warnings and
details. The most likely warning you are going to see is that your database uses an old timezone file. The upgrade of
the timezone file is mandatory, and needs to be completed using the instructions provided on My Oracle Support.
Database Upgrade Assistant also supports silent migrations, which can come in handy when you do not have an
X server available for security reasons.
Consolidating migrated databases
You read in chapter 7 that you could plug a non-Container Database (CDB) into a CDB. Transforming the freshly
migrated database into a Pluggable Database (PDB) is a logical consequence of the idea described earlier and a
further step to consolidation.
