Steps to upgrade

Import files to System Platform IDE

After completing the prerequisites and any applicable version-specific steps, import the following files in the exact order shown:

  1. ArchestrA.InTouch.SkeltaControls.dll to enable workflow features in InTouch HMI

  2. AVEVA Work Tasks controls for InTouch OMI

  3. WorkflowGateway object file, aaPKG or aaPDF

  4. Script function library (ArchestWorkflowScripts.dll)

    Import DLL files

    When you import the object into System Platform IDE, the following DLL files are stored in the ArchestrA Installation folder > Framework > FileRepository > CustomCategoryUIFiles folder.

    • ArchestrA.Workflow.IDEExtension.dll

    • Skelta.ArchestrA.WinForms.dll

    • Skelta.WinForms.dll

    • Skelta.WinForms.Security.dll

    If these DLL files are not added automatically, copy the files manually from C:\Program Files (x86)\ArchestrA\Workflow\IDEExtension to:

    • C:\Program Files (x86)\ArchestrA\Framework\FileRepository\CustomCategoryUIFiles

    • C:\Program Files (x86)\ArchestrA\Framework\Bin\IDEExtensions

    Verify that the files are available in the Framework\Bin\IDEExtensions folder under the ArchestrA installation path.

    If the files are missing, copy them manually. The Workflow tab in System Platform IDE > Workflow Toolbox is not displayed unless these DLL files are available.

    Import ArchestrA.InTouch.SkeltaControls.dll to use additional controls that enable workflow features in InTouch. For information about InTouch controls, see Workflow Status View Inside InTouch.

    Import ArchestrA App

    1. Open System Platform IDE.

    2. Select Galaxy > Import > ArchestrA Apps.

    3. In the Import ArchestrA App dialog box, navigate to: <Installation Path>\ArchestrA\Workflow\InTouchOMI\.

    4. Import the ArchestrA App.

      The imported ArchestrA App appears as AVEVAWorkTasksAppXXX in the Graphic Toolbox.

      Import WorkflowGateway object file

      The WorkflowGateway object file (.aaPKG or .aaPDF) stored in the AppObjects folder.

      1. Open System Platform IDE.

      2. Select Galaxy > Import > Object(s).

        1. In the Import Automation Object(s) window, navigate to: <Installation Path>\ArchestrA\Workflow\AppObjects

          1. Select the WorkflowGateway_XX.X.aaPKG file.

          2. Select Open.

          3. In the Import Preferences window, select OK.

          4. After the import completes, select Close.

          5. Close and reopen System Platform IDE.

            Import script function library

            To import ArchestrAWorkflowScripts.dll:

            1. Open System Platform IDE.

            2. Select Galaxy > Import > Script Function Library.

            3. In the Import Script Function Library window, navigate to: <Installation Path>\ArchestrA\Workflow\Scripts

            4. Select ArchestrAWorkflowScripts.dll.

            5. Select Open.

              Note:
              - Import the ArchestrA App only once. System Platform IDE allows multiple imports of the ArchestrA App by creating multiple objects with incrementing sequence numbers, such as AVEVAWorkTasksAppXXX, which can lead to inconsistencies.
              - During an upgrade, the existing WorkflowManagementApp is not overwritten. Delete the existing WorkflowManagementApp before importing the new version.
              - Before deleting the existing WorkflowManagementApp, ensure that it is not referenced by any ViewApp, Layout, or other objects. Otherwise, warnings may be generated in the logger.
