Migrating From Logica Sandbox to Meld Community Edition

Export your FHIR Bundles From Logica

The first step to migrating to Meld is you need to export all your FHIR Bundles out of Logica.

  1. Go to the Logica Sandbox you wish to migrate
  2. Go to the Data Manager
  3. Click on the “EXPORT” tab
  4. Click EXPORT ALL TO FILE
    • Logica will take some time to prepare the download
    • You will see progress of objects loaded
    • Keep this page open during this process
  5. Finally click the DOWNLOAD FILE button
    • You now have all your FHIR resources downloaded

Set Up Your Own Meld Sandbox Using Foundry

Now we will walk through the process of deploying your own Meld Sandbox on your own device.

The prerequisites to this tutorial is:

  1. Have a HL7 FHIR Foundry account
  2. Next you will need Docker Desktop or another container runtime

Launching Meld

Search “Meld” in the Foundry Catalog and you should find Meld Community Edition. Then click the “Download Stack with Defaults”.

Go to the command line and run:

docker compose -f docker-compose.yml up --pull always --remove-orphans

Here you can see that meld is beginning to spin up.

Setting Up Your Meld Sandbox

  1. Navigate too: http://localhost:3001/
  2. Register for an account

You should now reach My Sandboxes page. The next step is to create your “New Sandbox”. Once you click on the button you will name it, select the FHIR version you used on your previous sandbox, and uncheck “Import sample patients and practitioners”. Whether you want to “Import sample applications” or have “Allow Open FHIR Endpoint” on is up to you but we recommend having them on.

Press “CREATE” and you have now successfully made a new sandbox.

Import You FHIR Bundles

Now on how to import your Logica FHIR Bundles into your new Meld Sandbox. You will want to click on the sandbox you just made and navigate to the Data Manager.

This time you will click “IMPORT” tab and then the “LOAD FROM FILE” option in the top right. Choose the file you downloaded from your Logica Sandbox. (Should be sandbox-export.json)

Your import has begun and this process will take awhile for it to load. Do NOT navigate away from the window. This load will take more than 10 min. Upon completion you will see a results similar to one below:

Verify that your FHIR Resources are available.

You have successfully migrated to Meld Sandbox!
