Validation Pattern Deployment

If using validation pattern in a view or form, when you create a package (.kspx); validation pattern are included in the Additional Items section and will deploy to the target environment if does not exists.

If you make a change to a validation pattern, it will be included in the package but the default option will be use existing.  To update validation pattern in the target environment using P&D, make sure to change it to Overwrite Existing.

Validation pattern are global, so once you make a change to a pattern in any view/form, the update will affect any views/forms that uses it.  So in theory, you can also just use a test view or form in the target environment if you want to manually update a validation pattern.
