Lightroom: LR4.1: maintain exact look of previously (LR3) processed images when converting to 2012?

(previously posted here http://feedback.photoshop.com/photosh... but as Michael pointed out in a slightly unrelated thread)

am i correct in thinking that there's effectively no way to automatically keep the same visual appearance of older 2010 processed DNGs when converting to 2012? ran a minimal test, and it appears that the change goes beyond moving from medium contrast to linear for the curves. manually switching back to medium contrast on a converted shot still ends up with fundamental differences (contrast is far harsher) and possibly wrong values in the basic settings (even accounting for the fact that the values there have been rebased and changed).

see http://twitpic.com/978u8r and http://twitpic.com/978uav

this begs the question: if the suggested way to go is to just keep already processed old shots in 2010 (and having to force myself to ignore the "!" that helpfully reminds me that it's in the old process), can we have a guarantee that older processing algorithms/models will remain supported in all future versions of lightroom? and that we're not going to have a nice surprise in the next version bump, a la "this version drops support for anything other than 2012 process, sorry" (thinking about similar issues with Adobe Audition when they dropped support for non-XML format in the latest version, which meant having to manually go into each project with the old version and re-saving it in the XML format).

No, there is no way to automatically do this. It is suggested that you move to the new process only as you need to.

PV2003 is still supported so I wouldn't worry just yet.

Yes, you are correct.

But Tom Hogarty of Adobe has assured us that Lightroom will support old PVs "forever".

It wouldn't surprise me if at some point the photos, although still displayable/exportable under old PV, may no longer be editable when still using an oldest obsolete PV, but Tom Hogarty did NOT say that - it is strictly conjecture/speculation on my part - point being that they will never look different without you editing them.

Patrick,
We're well aware of the desire to maintain the visual appearance of a parametrically edited image over a long period of time. That's why we introduced the concept of Process Versions. Guaranteeing "all future versions" is a bit naive as we can't predict the future but we have designed our solution around that very goal and it's closely aligned with our business goal of maintaining a long term relationship with our customers.

Regards,
Tom Hogarty

personally, I export jpeg copies of the "final versions" of all images for which I consider editing as "finished", in folders of the same structure as my Lr catalogue (hoping that at least the jpeg format will still be readable in 20, 30 years from now... when applications like Lr may come and go).
