How to convert PostgreSQL to Oracle

Full Convert is designed for ease of use and reliability to make sure you get your job done as quickly and as simply as possible.

Source database is known as Postgres, PG

Making migration easy for you

Full Convert is a fully self-tuning software. Your migration will work as expected without you needing to adjust anything.

Data types are different in Oracle compared to the source PostgreSQL. We automatically adjust them as we copy the tables so you don't have to worry about it. You can adjust the mapping rules if you wish to change the following defaults:

  • bigint number(20)
  • bit number(1)
  • boolean number(1)
  • bytea blob
  • cidr varchar2(50)
  • citext clob
  • decimal number
  • double precision binary_double
  • enum varchar2(255)
  • geography sdo_geometry
  • geometry sdo_geometry
  • hstore clob
  • inet varchar2(50)
  • int number(10)
  • interval number(10)
  • json nclob
  • jsonb nclob
  • macaddr varchar2(50)
  • money number(19,2)
  • oid blob
  • real binary_float
  • smallint number(5)
  • text clob
  • time date
  • timestamptz timestamp
  • uuid raw(16)
  • varbit blob
  • varchar clob (if oracle_extended is true and precision > 32767)
  • varchar clob (if oracle_extended is false and precision > 4000)
  • xml xmltype

Full Convert migration in 4 easy steps

PostgreSQL connection

Connection to PostgreSQL

We will choose PostgreSQL from the list of available source database engines. Connecting to Postgres is straightforward - we need to specify server name/IP, username, password and database name.


Connection to Oracle

We will choose Oracle from the source database engines list. We can connect to our Oracle in two ways. If we have Oracle Client installed, simply typing the service name and specifying login info is all we need.

However, when you don't want to install 100MB+ of OCI installation, we have a nice surprise! We can connect to Oracle using a direct TCP/IP connection. No OCI required. In addition to database name and login info, we would just need to specify server name or IP - and done.

Oracle connection

Start the conversion

All source tables are selected for conversion by default. In case you only need some tables, simply deselect the ones you don't need - or deselect all, then select just the tables you do need. Click the Copy your database button to get started.



Conversion is highly-optimized to run as fast as possible, yet provides top-notch reliability. Huge tables are converted in small chunks at a time, preserving memory and ensuring that your computer stays fast and responsive.
