QuickOPC-UA migration path

QuickOPC-UA is scheduled for release in December 2011/January 2012. A <a href="/LinkClick.aspx?link=188&tabid=195">pre-release version is available to users registered on this site. The API is stabilized, and we are working on parts of the documentation, examples, and testing. Note that the Quick Start and Reference (!) documentation pieces are already available, and also some examples, though not many.
This initial version will only support an equivalent of "Data Access" in "classic" OPC. Because the OPC Unified Architecture is quite different from the "classic" OPC, the QuickOPC-UA will be a separate product that uses the basic design principles from QuickOPC-Classic, but it it has its own, separate classes (object model). OPC-UA can and will run alongside "classic" OPC, and similarly, QuickOPC-UA can be combined with QuickOPC-Classic in one application. For this reason, we do not consider going from QuickOPC-Classic to QuickOPC-UA a "migration", but rather an extension of existing system. Customers that own QuickOPC-Classic license may get a discount with QuickOPC-UA purchase (pricing model is not yet complete), but it will not be considered a version upgrade - it would be a purchase of a new product. Also, QuickOPC-UA will have its own versioning and release cycle, separate from QuickOPC-Classic.
Final note: If you have a system that already uses QuickOPC-Classic (QuickOPC.NET or QuickOPC-COM), and just need to connect to an additional OPC-UA server, you can do it already with QuickOPC-Classic, using the OPC UA COM Interop Components distributed with the product.

Hi,
Can you tell me when this will be available and what the migration path of the current Data Access and Alarm components will look like?

Thanks,
S.
