Configuring data-sources: Merging data-sources

We recommend using a manual sourceKey if you need to re-generate a database with existing user data (visualizations etc.), or when the hostname and port number of your data-source are likely to change after the first connection to Linkurious Enterprise.

Alternatively, you have the possibility to merge the data-sources directly from the data-source management page with the following steps:

1. Open the data-source management page.

From the dashboard, go to the Admin > Data-sources management menu

2. Select the old data-source to be merged.

The data-source to be merged should be the old data-source now marked as offline because it has been replaced with the freshly generated data-source.

3. Select the new data-source to be updated.

On the resulting modal, select the new data-source then click on the merge button.

The user can choose to perform a normal merge, or an overwrite merge.

1- Normal merge

As a result, the following objects from the old data-source will be merged in the new data-source:

  • Visualizations
  • Alerts
  • Graph Queries
  • Custom Actions

The Data-Source won't be deleted in case the user decides to do an overwrite merge at a later stage.

2- Overwrite merge

To perform an overwrite merge simply select the overwrite check box in the merge modal.

As a result, the objects from the old data-source mentioned above will be merged in the new data-source. Additionally, the following objects will be replaced in the new data-source with the ones from the old data-source:

  • User's default styles for new visualizations
  • Default styles & captions
  • Groups & access rights
  • Schema

This action will irreversibly remove any data associated with the old data-source, and the data-source will be deleted.
