Migrate to FinLinux OS

Supported migration paths

How FinShift works

FinShift swaps repository configuration, re-points package signing trust, and reinstalls every package from the FinLinux OS repositories to guarantee full binary parity — rather than only relabeling the existing installation.

curl -O https://raw.githubusercontent.com/finlinux-os/finshift/main/finshift
chmod +x finshift
sudo ./finshift analyze
sudo ./finshift convert
sudo reboot

The analyze step is non-destructive and reports any third-party or incompatible packages before you commit to convert.

Before you migrate

• Take a full backup or snapshot — FinShift is well tested, but any in-place OS conversion carries risk.
• Run finshift analyze first and resolve any flagged package conflicts.
• Confirm your target FinLinux OS version matches your current major version (cross-version migration is not supported by FinShift — use a standard major upgrade path instead).
• Schedule a maintenance window for the final reboot, even though the conversion itself doesn't require extended downtime.

After migration

Once converted, the system is a standard FinLinux OS installation — it receives errata through the normal FinLinux OS repositories and is indistinguishable from a fresh install at the package level.
