Official migration guide is now available on
Please be aware that this is still experimental and problems might be present. You
should read the documentation in its fullest before you attempt migration.
Do not attempt migration of Turris 1.x at this time. There is known problem with updater itself. You are going to end up with broken router. (https://gitlab.nic.cz/turris/turris-build/-/issues/179)
If you are going to perform migration on Turris 1.0 and Turris 1.1, be aware that Turris OS 5.0 provides only experimental support for these models.
