A website migration can look straightforward until someone asks where the event archive went, why a membership renewal link no longer works, or who owns the login for a critical form. It is a way to protect the information, member journeys, and staff processes your organization relies on every day. A migration is a rare opportunity to remove outdated material, clarify what members need most, and give staff a website they can maintain without creating a new administrative burden. Start With Decisions, Not Copying The most common migration mistake is treating every piece of existing content as equally valuable. Older association websites often contain years of expired event pages, duplicate resources, former board member bios, outdated program descriptions, and PDFs that nobody can identify.
