Upgrade from Gogs
=================

Gogs, version 0.9.146 and older, can be easily migrated to Gitea.

There are some basic steps to follow. On a Linux system run as the Gogs user:

*   Create a Gogs backup with `gogs backup`. This creates `gogs-backup-[timestamp].zip` file containing all important Gogs data. You would need it if you wanted to move to the `gogs` back later.
*   Download the file matching the destination platform from the [downloads page](https://dl.gitea.io/gitea/). It should be `1.0.x` version. Migrating from `gogs` to any other version is impossible.
*   Put the binary at the desired install location.
*   Copy `gogs/custom/conf/app.ini` to `gitea/custom/conf/app.ini`.
*   Copy custom `templates, public` from `gogs/custom/` to `gitea/custom/`.
*   For any other custom folders, such as `gitignore, label, license, locale, readme` in `gogs/custom/conf`, copy them to `gitea/custom/options`.
*   Copy `gogs/data/` to `gitea/data/`. It contains issue attachments and avatars.
*   Verify by starting Gitea with `gitea web`.
*   Enter Gitea admin panel on the UI, run `Rewrite '.ssh/authorized_keys' file`.
*   Launch every major version of the binary ( `1.1.4` → `1.2.3` → `1.3.4` → `1.4.2` → etc ) to migrate database.
*   If custom or config path was changed, run `Rewrite all update hook of repositories`.

Change gogs specific information
--------------------------------

*   Rename `gogs-repositories/` to `gitea-repositories/`
*   Rename `gogs-data/` to `gitea-data/`
*   In `gitea/custom/conf/app.ini` change:

FROM:

[database]
PATH = /home/:USER/gogs/data/:DATABASE.db
[attachment]
PATH = /home/:USER/gogs-data/attachments
[picture]
AVATAR_UPLOAD_PATH = /home/:USER/gogs-data/avatars
[log]
ROOT_PATH = /home/:USER/gogs/log


TO:

[database]
PATH = /home/:USER/gitea/data/:DATABASE.db
[attachment]
PATH = /home/:USER/gitea-data/attachments
[picture]
AVATAR_UPLOAD_PATH = /home/:USER/gitea-data/avatars
[log]
ROOT_PATH = /home/:USER/gitea/log


*   Verify by starting Gitea with `gitea web`

Upgrading to most recent `gitea` version
----------------------------------------

After successful migration from `gogs` to `gitea 1.0.x`, it is possible to upgrade `gitea` to a modern version in a two steps process.

Upgrade to [`gitea 1.6.4`](https://dl.gitea.io/gitea/1.6.4/) first. Download the file matching the destination platform from the [downloads page](https://dl.gitea.io/gitea/1.6.4/) and replace the binary. Run Gitea at least once and check that everything works as expected.

Then repeat the procedure, but this time using the [lastest release](https://dl.gitea.io/gitea/1.10.2/).

Upgrading from a more recent version of Gogs
--------------------------------------------

Upgrading from a more recent version of Gogs is also possible, but requires a bit more work. See [#4286](https://github.com/go-gitea/gitea/issues/4286).

Troubleshooting
---------------

*   If errors are encountered relating to custom templates in the `gitea/custom/templates` folder, try moving the templates causing the errors away one by one. They may not be compatible with Gitea or an update.

Add Gitea to startup on Unix
----------------------------

Update the appropriate file from [gitea/contrib](https://github.com/go-gitea/gitea/tree/master/contrib) with the right environment variables.

For distros with systemd:

*   Copy the updated script to `/etc/systemd/system/gitea.service`
*   Add the service to the startup with: `sudo systemctl enable gitea`
*   Disable old gogs startup script: `sudo systemctl disable gogs`

For distros with SysVinit:

*   Copy the updated script to `/etc/init.d/gitea`
*   Add the service to the startup with: `sudo rc-update add gitea`
*   Disable old gogs startup script: `sudo rc-update del gogs`
