By Mouhamadou Diaw<\/strong><\/p>\n

With Oracle 20c, the non-multitenant architecture is no longer supported. So, people will have to migrate their databases to container if they want to use Oracle 20c. There are many methods to transform a non-cdb database to a pluggable one.
\n-Datapump
\n-Full Trabsportable Tablespaces
\n-Plugging non-cdb database , upgrade the plugged database and then convert
\n-Upgrading the non-cdb database, then plug it the container and then convert it ( But I am not sure that this method will work with Oracle 20c as there is non-cdb architecture)
\nWe can find useful information about these methods in Oracle documentation and on Mike Dietrich blogs<\/p>\n

In this blog I am going to use the method plugging the database to migrate a non-cdb Oracle 19c database prod19<\/p>\n

The first step is to open the source database on READ-ONLY mode and then generate the metadata xml file of the non-cdb prod19 database using dbms_pdb.describe procedure.<\/p>\n

The generated xml file is used to plug the non-cdb database into the container prod20. But before plugging the database I run the following script to detect eventual errors<\/p>\n
