Migrato is an open-source PC migration tool. Run it on both computers on the
same network, pair them with a PIN and transfer your data over an encrypted
connection: known folders and custom folders, Mozilla Thunderbird and Firefox
profiles including passwords, settings of popular apps, installed programs
(reinstalled via winget), Wi-Fi networks with passwords, wallpaper and fonts.
Transfers verify every file with SHA-256 and resume after interruption.
Czech and English UI. No cloud, no telemetry, no Microsoft account required.
An open-source tool for moving your data to a new Windows PC — over Wi-Fi (local network), no cables, no cloud, no fees.
Run the app on both computers, a PIN appears on the new one, pick what to transfer on the old one, done. The UI is in English or Czech, following your Windows language.

Receiving (new PC)
What it transfers
Files — Desktop, Documents, Downloads, Pictures, Music, Videos, Favorites. Folders are resolved via Windows APIs, so OneDrive-redirected folders work too. Plus any custom folders from anywhere (including other drives) — they land on the new PC's desktop in “Transferred folders”.
Mozilla Thunderbird — the complete profile: accounts, mail, passwords, contacts, calendar, filters, add-ons.
Mozilla Firefox — the complete profile: bookmarks, passwords, history, extensions, open tabs.
Settings of other apps — Notepad++, VLC, FileZilla, OBS Studio, GIMP, LibreOffice, KeePass, VS Code, Windows Terminal, IrfanView, PuTTY, 7-Zip, WinRAR, Total Commander. Includes settings stored in the registry (HKCU). Missing apps are installed automatically via winget.
Chrome and Edge bookmarks — default profile.
Installed programs — reinstalled automatically on the new PC via winget import; a human-readable list of all programs is saved to the desktop.
Wi-Fi networks including passwords — the new computer connects on its own.
What it deliberately does not promise
Honesty is a core feature of this tool:
Chrome and Edge passwords cannot be transferred. They are encrypted by Windows DPAPI with a key tied to the specific computer and account. Use Google/Microsoft account sync instead. (Firefox and Thunderbird passwords do transfer — their key travels with the profile.)
Installed programs are not moved 1:1 — they are reinstalled via winget and their data is transferred. Programs not available in winget need manual installation (see the list on your desktop).
(Office activation, Adobe, etc.) must be transferred with the vendor.
(The app is stored outside the transferred folders on purpose — Migrato excludes the folder it runs from, so don't keep it on the Desktop or in Downloads.)
How to use it
Download Migrato.exe from Releases on both computers (or use the PowerShell quick start above). If your browser refuses the exe, grab Migrato-win-x64.zip instead and unpack it.
On the new computer run Migrato and choose “This is the NEW computer” — a 6-digit PIN appears.
On the old computer choose “This is the OLD computer” — the new computer shows up in the list (both must be on the same network). If it doesn't (NAT, VMs, separated subnets), use the manual IP:port connection shown on the new computer's screen.
Enter the PIN, pick what to transfer, start.
Close the apps being transferred (Thunderbird, Firefox…) on both computers first — Migrato warns about running processes.
Both computers are kept awake during the transfer. You can still interrupt it at any time — the next run resumes where it left off: finished files are only verified by checksum and skipped, the interrupted file continues from its last byte. Every file is verified with SHA-256 after transfer.
Existing files at the same destination path are overwritten — the tool is designed for migrating to a fresh computer.
> SmartScreen note: the exe is not code-signed yet, so Windows shows an “unknown publisher” warning on first run. Click More info → Run anyway. Code signing is planned once the project matures.

Troubleshooting
The old computer can't see the new one:
Both computers must be on the same network and subnet (check with ipconfig that e.g. both are 192.168.1.x).
Virtual machines (Parallels, VirtualBox, Hyper-V): switch networking to Bridged mode, or use the manual IP:port connection shown on the new computer's screen.
Firewall: allow Migrato on first run, or open UDP 42424 (discovery) and TCP 53425 (transfer) inbound for private networks.
Some routers have AP/client isolation enabled on Wi-Fi — devices can't see each other; use an Ethernet cable or disable isolation.
The transfer seems stuck: if the progress bar moves or file names change, it's working (verifying resumed data reads gigabytes from disk without network traffic). A genuinely dead connection fails on its own within ~30 seconds.
Security
All transfer traffic is TLS-encrypted (an ephemeral certificate per session).
Pairing is protected by the PIN: the sender proves knowledge of the PIN with an HMAC bound to the receiver's certificate fingerprint, so the PIN is never revealed and a man-in-the-middle fails even with a recorded exchange. The receiver locks the session after 5 failed attempts.
Data never leaves your local network. No cloud, no telemetry.
dotnet test # core tests
dotnet run --project src/Migrato.App # run for development
dotnet publish src/Migrato.App -c Release -r win-x64 --self-contained \
-p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -o publish
Development works on macOS/Linux too (Avalonia UI); Windows-only modules (winget, netsh, registry) disable themselves elsewhere.
Architecture
src/Migrato.Core library: discovery (UDP broadcast), TLS + PIN pairing,
transfer protocol with resume and SHA-256 verification,
migration modules (known folders, app profiles, winget, Wi-Fi)
src/Migrato.App GUI (Avalonia, MVVM), Czech/English
tests/ unit tests + an integration loopback transfer over real TCP/TLS
Supporting another app = one new entry in src/Migrato.Core/Modules/app-profiles.json (where the app keeps its data, process name, winget id) — no new code.
