Legacy Migration

HoloISO installer, since version 1.1 supports migration from non-immutable HoloISO release, and is available on the downloads page as of now.

There are some precautions to be taken:

1. If possible, take a backup, who knows what could possibly go wrong?
2. After booting to installer, press on "Migrate RW to RO"

Important notice

Dual-booted systems require manual intervention, look at Dual-boot, Migrating older dual-boot installations page for more info

1. You will be asked to enter password for your current user, enter it, and grab some hot beverage while new system is being installed
2. Reboot and enjoy!
