TLDR: Are there people who have worked on "ageing of pages" which will be replaced/removed in X months. Is there existing research on this topic we can use, or known issues we should learn from.
Full: We are working on making significant changes on our internal products, we're introducing new flows to replace existing flows that have existed over a decade. We are planning to sunset the existing flows in the next 24 months or so.
We have worked on the standard communication and process to smoothen the transition for our users, and made a small roadmap in how to phase out our existing stack.
Because our users appreciate some light hearted fun; we are thinking of degrading the pages that support the existing flow over time. We are looking for some patterns or metaphors we could use. Ideally we show the degradation of the pages without affecting the functionality. There will be some functionality changes, but those are tied to the sunsetting of sub flows.
We are asking if anybody already has done anything like this. Or if people know if there is research on the concept of "visualising the ageing process of digital content". There might be some caveats we can should prevent.
With our designers we already though of some simple analogies like "spider webbing on the headers" or small cracks in the design, introducing some staining/rust here and there, and increase that over time.
We realise that this might not meet the standards of typical professional design questions asked here. At the same time we thought it was an interesting enough concept to think about, as we haven't seen much discussion about the ageing of digital content in general.
Thanks a lot for your time.
