About this task

If you’re an upgrading user, and you want to migrate your existing pipelines steps to change models, you must perform this procedure.

The DevOps Pipeline Migration to Change Models catalog item enables you to update the change model in each step record in your pipeline at once. For example if you have set the type compatibility com.snc.change_management.change_model.type_compatibility  property to false and change model input is required in multiple pipeline steps, you can use this catalog item to update the change model for all pipeline steps in one go.

Procedure

1. Navigate to  All > Service Catalog > Catalog Definitions > Maintain Items > DevOps Pipeline Migration to Change Models, and set the  Active  state to  True  to activate the  DevOps Pipeline Migration to Change Models maintain item.
   By default the catalog item is turned off.
2. In the Available For related list of the catalog item, add the users to whom the catalog must be available.
3. In the Approve By related list of the catalog item, add the users who can approve the catalog item.
   Alternatively, navigate to  All > Flow Designer > Flows, and activate the  Request for pipeline migration catalog flow. You can update the rule set in the  Ask For Approval  action of the flow to add a user or a group of users who can approve the catalog item.
4. To add the catalog item in the Service Catalog categories in Service Portal, set the category of these items to  DevOps  and add the  Service Catalog  catalog.
   If the  DevOps  category isn’t available, you must create a new category called  DevOps  from the catalog item record itself and assign the  DevOps Onboarding  catalog to it.
5. To add catalog item in Employee Service Center, add a new topic in the  Assigned Topics  related list with taxonomy as  Employee  in the  IT > IT for IT  section.
   The Assigned Topics related list isn’t available in the Default view of the Catalog Item form. To add it, select  Additional icons > Configure > Related Lists  and move the  Connected Content → Catalog item   field to the selected section.
6. Navigate to  All  >  Service Catalog  >  Catalog Definitions  >  Maintain Items  and search for DevOps.
