COM Import Upgrade Considerations

If you have used the COM Component Import feature, CA recommends that you reimport and regenerate the imported COM packages as part of the release upgrade process. This is due to fixes and improvements to the COM import and wrapper generation processes at this release. You may need to revise the wrapper attributes of the package before it compiles. Note the following:

• The COM Component Import wizard provides an option Do not overwrite existing package. However, clearing this option is not appropriate for upgrading previously imported COM packages.
• An alternative is to delete the COM package object before running COM Component Import. However, this will invalidate existing action diagram statements that reference the COM package.

To avoid these limitations, the following upgrade procedure is recommended:

1. Create a new group model and attach the COMPONENT library.
2. Extract a new local model and use the COM Component Wizard to import a new COM package for component you need to upgrade.
3. In Object Browser, right-click the COM package and select XML Import from the Tools menu. Export the package to a named XML file.
4. Open a local model containing the COM package that you need to upgrade.
5. From the Tools menu, select Import and then XML Import. Select the Clear option and then import the XML file you created earlier.

The above procedure will upgrade the COM package while preserving existing action diagram code.
