Data Migration to New PACS

Good morning,
How to migrate Orthanc Dicom Pacs to other Pacs?

I need to migrate the data stored in Orthanc (about 1 TB) to another Pacs. Are there any rules or guidelines available how to perform this migration? How can I verify this process perfectly?

Does anyone have experience?

I use Orthanc on windows.

Thaks,
regards

Giogio

Hi Giorgio,

There are several ways to achieve that goal.
I would go for a python script which would query the Orthanc API in order to send the studies to the PACS.
Regarding the verification, you can query the PACS (after each study transfer) in order to get the number of instances and compare it with the number of instances in Orthanc.

Regards,

thanks for the quick response

unfortunately I don’t know python,
the script already exists? How can I connect it to orthanc? Can you help me?

Otherwise with q / r from orthanc is it possible?

Exactly how can I extract the number of instances from a pacs?
I can verify the number of studies, but it is not a 100% reliable value.

Thanks again

The answer depends on your target PACS.

If you are not using a storage plugin for Orthanc (MySQL/PostgreSQL) and if you let the “StorageCompression” configuration option of Orthanc to its default value (“false”), you can access all the DICOM files directly from the filesystem in the “OrthancStorage” folder:
