25> On Windows, earlier Claude Desktop releases stored this data under `%APPDATA%\Claude-3p\` (the Roaming profile). On first launch after upgrading, the app moves the existing directory to `%LOCALAPPDATA%` automatically; if Roaming is redirected to a network share, conversation history and configuration are copied and large regenerable caches are re-downloaded. Update any external tooling, backup jobs, or endpoint policies that reference the old path. macOS paths are unchanged.
25> With the MSIX installer on Windows versions before Windows 11 (build 22000), for example on Windows 10, this directory can be at `%LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Local\Claude-3p\`, so check there too. On a device that used Claude Desktop on Windows 10 before it was upgraded in place to Windows 11, data from before the upgrade can still be at that `Packages` path.

27> On Windows, Claude Desktop versions earlier than 1.5186.0 stored this data under `%APPDATA%\Claude-3p\` (the Roaming profile). On first launch after an update from one of those versions, the app moves the existing directory to `%LOCALAPPDATA%` automatically, unless `%LOCALAPPDATA%\Claude-3p\` already exists. If Roaming is redirected to a network share, conversation history and configuration are copied and large regenerable caches are re-downloaded. Update any external tooling, backup jobs, or endpoint policies that reference `%APPDATA%\Claude-3p\`. With the MSIX installer, data from those versions can still be at `%LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude-3p\`. macOS paths are unchanged.

29> An uninstall or a reset of the MSIX package can delete the data at a `Packages` path.

315On Windows with the MSIX installer, contact your Anthropic representative before you copy the data to the new device if at least one of these is true:
316
317* The Windows build of one or both devices is below 22000 (for example, Windows 10)
318* On the old device, the user's `C:\Users\<user>\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache` folder has a `Local\Claude-3p` or `Roaming\Claude-3p` folder
319
