Is there a projected date of when PPDesign 7 documents will no longer be usable in PlanetPress Connect Workflow (via the PPS/PSM Documents folder)?
As we work to re-create our collection of PPDesign 7 documents in the Connect Designer application, a estimated date would assist greatly for migration planning purposes.
There is no such anticipated date. Even if one day there is, you can expect a good delay between end of life of PlanetPress Suite and its announcement.
To add to hamlj’s answer: our policy is to maintain support and as much backward compatibility as technically possible for a minimum of 5 years after a product is retired.
And PlanetPress Suite has not been retired. So you have quite a few years ahead of you, but that doesn’t mean you should delay enjoying the benefits of Connect!
