Note: The Upgrade may be run multiple times on the same or different MDB's in the same project without causing any corruption. However you must make sure that all databases containing MDS supports are run through this Upgrade procedure at least once.

It is advisable but NOT compulsory to complete this Upgrade process before any new MDS supports or any other new database elements are created in a project.

It is good housekeeping for you to Date stamp all of the upgraded 12 project databases before proceeding with this Upgrade process on an Upgraded 12 project.

The Upgrade process should be started in the MDS 11.6 project application and completed in MDS12 project application.

  1. The Design module Upgrade process for the MDS12 version is as follows. For example, copy the new MDS12 PML function supplied with the MDS12.0.SP5 version:

    ...\pmllib\design\functions\mds116DesignFor12Upgrade.pmlfnc

    into the corresponding PMLIB folder:

    ...\pmllib\design\functions, in the existing MDS11.6 appware.

  2. From within the existing 11.6 project MONITOR module, type PML REHASH ALL on the command line.

    Note: The user MUST have write access to the MDS11.6 PMLLIB folders for this to update the "pml.index" file.

  3. Enter an appropriate MDB containing MDS supports and generate the Upgrade macro file for the selected MDB by running the new PML function via the command line: For example:

    !!mds116DesignFor12Upgrade().

  4. Transfer the Upgrade macro file from the current 11.6 project folder into the corresponding folder of the target Upgraded 12 version of the project.

  5. Run the Upgrade macro on the command of the Design module of the Upgraded 12 project. For example:

    $M/C:\AVEVA\Plant\MDS12.0.SP4\project\mde\mdeinfo\ MDS12DesignAttaUpgrade\MDS116-to-MDS12-DESIGN-ATTA-UPGRADE-MACRO-27Aug2009-105747.pmlmac

  6. Running the Upgrade macro file will automatically generate an Upgrade Log file in the same folder of the Upgraded12 project as the Upgrade macro file itself. For example:

    C:\AVEVA\Plant\MDS12.0.SP4\project\mde\mdeinfo\MDS12DesignAttaUpgrade\MDS12-DESIGN-ATTA-UPGRADE-LOG-FILE-27Aug2009-105747.pmllog.

  7. A successful Upgrade will not generate any other data except for that shown below:

    <START of MDS12 DESIGN Module PROJECT UPGRADE LOG FILE>

    *** If there are NO SCREEN ERRORS and the UPGRADE LOG FILE is EMPTY the MDS ATTA and PLAT DESIGN Module PROJECT UPGRADE was SUCCESSFUL ***

    <END of MDS12 DESIGN Module PROJECT UPGRADE LOG FILE>
