Steven Hawkins commented on TEIID-5657:
---------------------------------------

> Did you add the .vdb support?

No, it is not there.

> I thought Steven Hawkins mentioned .vdb is not supported, which may be key here.

Without having worked out all of the issues related to vdb resources - arbitrary files, and jars, single potentially large ddl file, etc. - it's ok to not offer it at TP1 and rather start with .xml version that can be exported out of designer and validated in the old environment.

It doesn't appear yet that tsb is handling override translators, do you want an issue on that?

> A migration tool will be provided to convert customer vdbs into just ddl. More than likely this will be just a single ddl file - which will probably not be acceptable to customers with large vdbs.
> We have this utility already available as just a main method in one of our jars. It is anticipated that a maven repo will be distribution mechanism and minimal documentation will be provided.
> There should be optional validation available for the vdb ddl at build time. This breaks down into 3 parts:
> 1. static syntactic validation, potentially even fully resolving if all metadata is present. This makes sure that basic typos will be caught.
> 2. providing hard errors for things that are completely removed - an error for usage of soap or function models for example.
> 3. providing errors or warning for features that are not yet available - vdb imports, sources that aren't yet supported etc.
> To avoid introducing a new plugin or plugging into fmp it's been suggested that the validation could be run via a generated unit test, which ties into another task which is booster, base project, or last resort an arche type that scaffolds the developer project.
> This could possibly be included in the quickstarts as a means to facilitate its use.
