The dialog box will display a warning-type message that recommends to minimize customizations during the release update process as the environment quota is shared between both the build place and release update studio [1].

Steps to fetch the Release Update to the Customer Baseline Repository

  1. Select the delivery tag from the Delivery Tags dropdown [2] (Figure 2.1).

    The Delivery Tags dropdown will list down all the approved deliveries related to the current App version in the descending order. The last approved delivery will be listed on top and will be selected by default. The delivery selected from this dropdown, will be used to create the release-update branch when fetching the release update to the Customer Baseline Repository. It is recommended to select the delivery tag related to the latest delivery deployed to the production environment of the use place. The reason for this recommendation is due to the fact that the latest approved delivery may not always be deployed to the production environment, it may still be in the testing stage in one of the non-production environments.

  2. The latest Service Update for the release selected in the Request Release Update step will be shown in the read-only text field [3] (Figure 2.1).

  3. Upon clicking on the "Change Service Update" button [4], button gets disabled and "Target Service Update" text field [3] turns to a drop-down field by giving the possibility to select any service update released under the requested release version(Figure 2.1).

    Following image shows how the user can switch between service updates to select the "Target Service Update" to apply release update in the Baseline repository(Figure 2.2).

  5. Once both parameters are selected, the "Apply" button [5] shall be clicked to trigger the release update pipeline (Figure 2.1).

  6. If the decision is made not to proceed with the upgrade at this point, the "Cancel" button [6] shall be clicked to terminate the process (Figure 2.1).

Backend processes of fetching the Release Update to the Customer Baseline Repository

  1. The solution set will be fetched from IFS Biz and it will be stored in the relevant storage account in Azure.
  2. Central Build Services (CBS) will then migrate the Build Place related settings to its corresponding Release Update Studio.
  3. CBS will create parallel repository branches in the Azure devops project and will set branch policies to release-update branch.
  4. CBS will then remove all core code except version.txt file from release-update branch.
  5. version.txt file will be updated to the new version in customer-baseline repository release-update branch.
  6. CBS will finally fetch the solution set from the Azure storage account, commit to the customer-baseline repository and run the Baseline Build.
  7. This will result in following outcomes:
    1. Creating the release-update branch in the customer-baseline repository with the new release update and the solution set.
    2. Creating the release-update branch in the customer-solution repository from an approved delivery tag.
    3. Removing all core code (except the version.txt file) from release-update branches in both customer-baseline and customer-solution repositories.
