Create a topology version

Log on to the Scalable Open Financial Architecture Stack (SOFAStack) console.
In the left-side navigation pane, choose Middleware > Task Scheduling > Task Orchestration.
Click the name of the target in the topology list and then click the Version Management tab.
Click Add Version. In the dialog box that appears, select a baseline version for the new version.
Important
You can select only a published or archived version as the baseline version. A version can be selected as the baseline version for only one version being edited.
Click OK.

Edit a topology version

You can edit only versions in the Editing state. To edit a published version, create another version based on the target version.

In the version list, click Edit on the right side of the target version.
Edit the topology as required.
For more information about the editing procedure, see Edit a topology.
Click Submit.

Publish a topology version

For a newly created topology, the initial topology version is in the Editing state by default. You must publish this version before you use the topology.

In the version list, click Publish on the right side of the target version.
You can publish only versions in the Editing or Archived state. If a version in the Published state exists for a topology, the version automatically enters the Archived state after a new version is published.
Click OK.
You can view the published tasks on the Task Topology tab.

Discard a topology version

After a new version is published, the previously published version enters the Archived state. You can discard an archived version. A discarded version cannot be published again or used as the baseline version of a new version.

In the version list, click Discard on the right side of the target version.
Click OK.

Delete a topology version

You can delete a discarded version from the version list. A deleted version cannot be recovered. Proceed with caution.

In the version list, click Delete on the right side of the target version.
Click OK.
