PACS archive data migration

Martijn Klavers has been working as an IT engineer for 12 years at the Radiology and Nuclear Medicine division of the Universitair Medisch Centrum Utrecht. A great period in which he participated in a number of impactful changes. In 2018, the physical hardware had to be replaced by a virtual environment, in other words an extensive process.
Martijn: “Immediately after it appeared that the first data migration of the archive was not successful, we asked E-Storage to help after the previous good experiences. After E-Storage performed a successful PoC, I was immediately confident that it would work out. E-Storage made solid agreements with the application supplier Sectra and the UMC Utrecht.”
E-Storage and the Radiology and Nuclear Medicine division have previously collaborated on hardware support for the old PACS. “That went really well back then. The people at E-Storage listen carefully to what we want and know what is important for our hospital. They are super up-to-date with knowledge of different applications, think out-of-the-box and quickly come up with simple solutions. They simply arrange what is needed. Fast and accessible services, exactly what we need”, says Martijn.
It was extremely important to get an exact copy of data from location A to location B. That involved millions of files. During the data migration of the PACS archive, the old environment had to keep running. After the Radiology and Nuclear Medicine division had built the new virtual environment, all servers were set up and the new archive was subsequently attached to it, the old environment went out and the new one turned on. The business side has not been bothered by anything during this extensive process; partly thanks to the successful data migration by E-Storage!
Secure data migration for radiology UMCU

The Radiology department of the UMCU is one of Europe’s largest departments in terms of equipment and manpower. Around 500 patients visit the Radiology Department every day. They perform around 180,000 actions a year, including 25,000 MRI scans, 27,000 CT scans and 70,000 X-rays. The infrastructure on which the images were stored was outdated. Sectra was responsible for the old infrastructure, the Radiology department of the UMCU built the new one. The challenge was to migrate the existing images to the new environment. It involved millions of images, totaling 120 terabyte.
At that time, e-Storage proposed a Migration Proof of Concept (Poc). The application that used e-Storage to migrate the images (Datadobi) had several advantages over the open source software that Sectra used itself, including: data verification, the ability to see per file what is going well and what is not, easier management of large batches and the possibility to include users and shared folders in the migration. The results of the PoC were so good that e-Storage took over the assignment from Sectra for the complete data migration.
The data migration took place over a period of 2 months. While the Radiology department of the UMCU built the new environment, e-Storage migrated the data. The old image archive remained available throughout the entire period. At the time of the switch-over to the new environment, all images were transferred securely and completely.
“Data migration is something very beautiful. To be able to do it properly, you have to think outside the box. See the whole and the possibilities. As a knowledge center, we have added value. Many companies understand a piece of IT: storage, data, application, infrastructure, but e-Storage has knowledge of all those different pieces. A customer question is a team effort for us, internally picked up by a team and together with the customer as a team. This way we can combine different pieces of knowledge into the best solution for the customer.” (Thijs van Weegen, System Engineer)
