Plain-English answer
The legacy conference site should be preserved as an archive, not rewritten into current guidance. It documents an earlier institutional moment: event pages, program material, sponsors, attendee information, and conference-era positioning. The current site should point archive links to /legacysite/ and should make clear that present-day healthcare analysis belongs in the main reference pages.
Preservation rule
Archive preservation has two goals: continuity and clarity. Continuity means old content remains reachable for users, search engines, and anyone looking for the historical conference material. Clarity means a reader should not mistake old program text for current analysis of FDA, CMS, NMPA, NHSA, hospital procurement, or healthcare reform. The archive should preserve layout, images, stylesheets, and linked pages where practical, but it should not be mixed into current topic pages as if it were evidence about today's healthcare system.
Because the legacy site has been integrated into a single /legacysite/ destination, the main site should use archive links sparingly and consistently. Current pages should not scatter readers into old attendee, ticket, program, or sponsor paths when the user's intent is to understand a modern healthcare topic. The archive is best used when the reader is explicitly looking for the historical conference record.
Separation from current content
The main site and the archive serve different purposes. The main site is a current reference library about U.S.-China healthcare systems, payment, regulation, hospitals, public health, life sciences, digital health, and market entry. The archive is historical documentation of the earlier conference presence. A page about U.S. reimbursement, China market access, or public hospital reform should use current primary sources. A page about the conference's origins or historical site should link to the archive.
This distinction protects readers. A sponsor page, ticket page, or event program can be valuable evidence of what the organization did at the time, but it cannot answer whether today's CMS payment rule, FDA guidance, NHSA procurement policy, or NMPA pathway has changed. The archive is evidence of history, not evidence of current operating rules.
Linking and search
Archive links should point consistently to /legacysite/ so users are not sent to scattered or outdated paths. The search index can include archive entries as archive destinations, but excerpts should not compete with current reference pages for policy or strategy queries. If an old page contains useful historical context, the current page should summarize the context in present-day language and link to the archive as a historical source.
Preservation also means resisting unnecessary rewriting. Old conference language can remain historically accurate even when it is no longer current. The appropriate fix is labeling, separation, and stable routing, not silently turning archive material into modern analysis. Current pages should carry current source links; archive pages should show what the organization published at the time.
