Moved a year of Claude Project memory into Claude Duet with a numbered handoff pack, tested it with questions only the old project could answer, and kept a shared log.

I was deeply invested in the Claude Projects ecosystem. I’ve worked with one Claude project for the better part of a year. It knows how I write, the rules I’ve given it, what I’m in the middle of, and a lot of history I’d rather not explain twice. Duet already knew a little about me from my account memory, but almost nothing that lived inside that project. So I tried bringing it over. This is new so I can't confirm how well it'll hold it long term, but this is what I did: 1. Export the project’s memory first: What a project remembers stays inside that project, so Duet couldn’t see any of it. I had the old Claude write all of it out to one file. 2. Have the old Claude build a handoff pack: Numbered files: a 'Start Here' file with my standing rules, the memory export, background on me, the history of the work, then overviews of the bigger projects. 3. Date everything and make sure newer files rule the hierarchy 4. Upload in order, then test it: I asked it things only the old Claude would know before trusting it with real work. 5. Keep one shared log: I’m keeping the old Claude Project around for now, so both of them write to one Google Doc (I have a folder that is synced to the claude that both Old Claude and Claude Duet have access to): The idea is that neither one ends up working from its own version of events. Is anybody else transferring detailed history and lore from Old Claude to Claude Duet?
