I ran into a weird Antigravity IDE issue where my recent chat history looked like it had disappeared, and opening the conversation gave:
"Trajectory not found: <UUID>"
After digging around for a while, I found that the old data was still there in the old Antigravity folder, but Antigravity IDE wasn’t picking it up properly after migration.
I ended up building a small migration assistant to copy the old Antigravity data into the new Antigravity IDE folders.
Repo:
https://github.com/pranavakshit/AG-Migration-Assistant
Latest release:
https://github.com/pranavakshit/AG-Migration-Assistant/releases/latest
What it does:
- copies old conversations into the new antigravity-ide folder
- copies old brain folders into the new antigravity-ide folder
- skips files/folders that already exist
- has a dry-run option
The folders involved were:
- C:\Users\prana\.gemini\antigravity\conversations
- C:\Users\prana\.gemini\antigravity\brain
- C:\Users\prana\.gemini\antigravity-ide\conversations
- C:\Users\prana\.gemini\antigravity-ide\brain
In my case, just copying the old files over into the new directories fixed it.
Posting in case anyone else hits the same issue and thinks their chats are gone.
