Streamlined Oracle to PostgreSQL migration
Getting Started β’ Running the Migrator β’ Contact
CYBERTEC Migrator is a streamlined and user-friendly tool that helps you to organize and efficiently migrate multiple Oracle databases to PostgreSQL. In addition to migrating your data professionally and securely with minimum effort, CYBERTEC Migrator allows you to visually monitor and track the whole process at any time.
Do you want to know if the Migrator can migrate your Oracle database to PostgreSQL? Then get the Migrator Trial Edition, a free version of the CYBERTEC Migrator, follow the offline instructions provided in Getting Started section, and try it out.
| π‘ | The Trial Edition of the CYBERTEC Migrator is exclusively intended for private or testing purposes, unless explicit authorization is obtained. |

The blog article Meet the CYBERTEC Migrator provides a good introduction on how to migrate Oracle's HR demo schema to PostgreSQL. Alternatively, you may want to watch the complementary CYBERTEC Migrator YouTube playlist.
Product Demo
For detailed information see the list of supported migration features for Oracle.
For older releases see Release Notes.

- Migration List:
- Display migration status in list
- Wrap long connection strings
- Structure stage:
- Detect Index Organized Tables and automatically exclude their overflow tables
- Data stage:
- Show total bytes and bytes per seconds for a finished transfer
- Indicate whether a child process died from a signal, such as from the out-of-memory killer
- Gracefully handle
INTsignals to hasten abort request
- Migration Settings:
- Changed data progress interval unit from milliseconds to seconds
- Migration passwords are now encrypted within the database
- Code editors occasionally loose changes while typing
- Renaming a table column does not display the new name in the constraint tab
- PostgreSQL reserved identifiers are not read if the amount of CPU cores can not be retrieved
- Replacing trigger code using the
Searchtab does not update the code in the editor without refreshing ORA-01652: unable to grow temp segment in tablespace TEMP by 1MB during operationwhen reading indexes from some Oracle databases- Enabling the diff mode on a view-editor causes a page crash
DEFAULT is not allowed in this contextwhen migrating list partitions with a non-uppercasedefaultstatement
CYBERTEC Migrator is distributed as a set of container images that are managed with the help of Docker Compose.
dockerdocker compose(>= 2.0.0)git(>= 2.20.1)bash(>= 4.0)
The CYBERTEC Migrator images can be obtained via two channels
- Online installation via container registry

The configuration provided with this repository starts the CYBERTEC Migrator on the standard HTTPS port.
The EXTERNAL_HTTP_PORT variable in the .env file (generated by ./migrator configure) controls the choice of port on which the Migrator is served.
If you don't have access to an Oracle or PostgreSQL database to test the Migrator, use our Migrator demo database environment.
