Avoiding duplicate workflows

Update sets manage the published state of all versions of a workflow prior to committing the workflow version on a local instance.

The last version of a workflow committed as an Insert or Update using an update set becomes the currently published version, regardless of the publishing sequence for the workflow versions.

Commit a workflow in an update set

Follow the steps in this page to commit a workflow in an update set.

Procedure

1. Workflow A - Version 1 is created and published in Update Set A.
2. Update Set A is completed and migrated to a local instance.
3. When the update set is committed, the system sets all prior versions of Workflow A to published = false.

   In the first migration, there are no prior versions.

4. Workflow A - Version 1 becomes the only published version of the workflow.

Update set migration example

It is not possible to have multiple published versions as a result of update set commits. However, this does not eliminate risk, and care should be taken when migrating update sets.

Consider this example:

1. Workflow A - Version 1 is migrated and committed to the production instance.
2. Update Set B is created.
3. Update Set C is created.
4. Workflow A - Version 2 is published in Update Set B.

   A customer update record is added to Update Set B with the Version 2 payload.

   A customer update record is added to Update Set B with the Version 1 workflow left unpublished.

5. Update Set B is completed.
6. Workflow A - Version 3 is published in Update Set C.

   A customer update record is added to Update Set C with the Version 3 payload.

   A customer update record is added to Update Set C with the Version 2 workflow left unpublished.

7. Update Set C is completed.
8. Update Set C is migrated and committed to the production instance.

   Workflow A - Version 1 is set to unpublished.

   Workflow A - Version 2 update is skipped since Update Set B, which contains Version 2, was never migrated.

   Workflow A - Version 3 is committed and becomes the only published version of the workflow.

Update set migration risk

Update Set B is migrated and committed to the production instance.

1. Workflow A - Version 3 is set to unpublished.
2. Workflow A - Version 1 remains unpublished.
3. Workflow A - Version 2 is committed and becomes the only published version of the workflow.

   The workflow has gone back a version, perhaps unintentionally. The regressed version becomes the currently published version.
