Dataphor has an upgrade system with versioning in libraries, but it has proven overly difficult to use and doesn't handle interlibrary upgrade ordering properly and so a simpler, largely manual scheme has arisen. It basically works like this:
- Make the changes to the D4 scripts
- Unregister w/o reconciliation (assuming library already registered)
- Register w/o reconciliation
- Run the results in a
That's basically it, except that if your changes involve adding a required column, the script that results from the first DeviceReconciliationScript invocation will create the column nullable so that you can run a script to default the column. Running DeviceReconciliationScript again will result in a script that turns the column not nullable.
We do have plans to address this aspect in general.
