Database Instances

The Database Instances page provides an overview of the current source types that have been scanned and uploaded into mConsole, the OpEx and rCapEx of retained or retiring existing sources, and the total OpEx (Current and Future) and rCapEx (Current and Future) costs for all sources that have been selected to be migrated, retained, or retired within the project.

The page displays the following sections:

The Database Instances section allows defining which sources will be migrated, modernized, retained, or retired. This designation determines the OpEx and rCapEx costs displayed on this page as well as on the Project Details page and the TCO Projects page.

Choose Projected Pathway for Source

Each source on the TCO dashboard is assigned a Projected Pathway based on the future plans for this source. Sources can go down a path of Migration, Modernization, Retention, or Retirement.

During the migration project, the sources in this pathway will be migrated from their current environment.

The pathway selected for the available sources influences the data shown on the relevant sections of the Database Instances page:

• Sources selected for migration, retention, or retirement, sorted by the engine type.

• Duration of the migration.

• Projected future costs due to migration, retention, or retirement.

Migration Pathway

To configure a source to follow the Migration pathway, on the Migrating tab, press the Add button. The instance settings dialog opens.

In the case if a multi-vendor license, the target vendor is selected before the instance settings dialog opens.

   • If selecting the instance from the dropdown list, press the Confirm button.

   • If creating a new instance, fill in the New Instance form:

     1. Specify Instance Group, Instance Name (shall be unique), and Target Platform.

     2. Depending on the target platform, fill in other required fields. For more details about creating target instances, see Cloud Instances.

3. Press the Confirm button.

For the Amazon target vendor, configure a source to follow the Migration pathway according to the cloud instance creation form.
