The last supported version of Forgejo which supports migration from Gitea is
29
+
*10.0.x*. You should *NOT* try to migrate from Gitea to Forgejo `11.x` or
30
+
higher without first migrating to `10.0.x`.
31
+
32
+
See [upstream migration guide](https://forgejo.org/docs/latest/admin/gitea-migration/)
33
+
34
+
The last supported version of *Gitea* for this migration process is *1.22*. Do
35
+
*NOT* try to directly migrate from Gitea *1.23* or higher, as it will likely
36
+
result in data loss.

In order to migrate, the version of Forgejo needs to be pinned to `10.0.x`
42
+
*before* using the latest version. This means that nixpkgs commit
43
+
[`3bb45b041e7147e2fd2daf689e26a1f970a55d65`](https://github.com/NixOS/nixpkgs/commit/3bb45b041e7147e2fd2daf689e26a1f970a55d65)
44
+
or earlier should be used.
45
+
46
+
To do this, temporarily add the following to your `configuration.nix`:
47
+
48
+
```nix
49
+
{ pkgs, ... }:
50
+
let
51
+
nixpkgs-forgejo-10 = import (pkgs.fetchFromGitHub {
52
+
owner = "NixOS";
53
+
repo = "nixpkgs";
54
+
rev = "3bb45b041e7147e2fd2daf689e26a1f970a55d65";
55
+
hash = "sha256-8JL5NI9eUcGzzbR/ARkrG81WLwndoxqI650mA/4rUGI=";
56
+
}) {};
57
+
in
58
+
{
59
+
services.forgejo.package = nixpkgs-forgejo-10.forgejo;
60
+
}
61
+
```

This will migrate the state directory (data), rename and chown the database and
···
48
84
chown -R forgejo:forgejo /var/lib/forgejo
49
85
systemctl restart forgejo
50
86
```
87
+
88
+
Afterwards, the Forgejo version can be set back to a newer desired version.
