migration from gogs to gitea with less pain

High level operation:

The main idea is to do a copy. The script will take the users from csv data from gogs, previously obtained, and will create gitea users interacting with gitea API

source := gogs.mysql --> select * from user; --> csv

dst:= gitea.postgres --> API /admin gitea -->  go script read from csv and http post to gitea api
copy(dst, source)

users migration

Export results of this query to .csv to migrate the users

SELECT * FROM user
WHERE email !='';

Execution:

CONFIG_FILE=./app.yml go run ./cmd/users/main.go

orgs migration

Export results of this query to .csv to migrate the users

SELECT
    u.name,
    ou.org_id,
    uo.name AS owner_name,
    uo.email AS owner_email
FROM org_user ou
INNER JOIN user u ON ou.org_id = u.id
INNER JOIN user uo ON uo.id = ou.is_owner

Execution:

CONFIG_FILE=./app.yml go run ./cmd/org/main.go

repositories migration

You have to options: You can use the API to import them or like I did: manually import using the unadopted button from the UI.

Execution:

CONFIG_FILE=./app.yml go run ./cmd/org/main.go

collaborators migration

Export results of this query to .csv to migrate the repositories

SELECT
    r.name AS repo_name,
    uo.name AS repo_owner,
    u.name AS collaborator_user,
    co.mode,
    CASE
        WHEN co.mode = 1 THEN 'read'
        WHEN co.mode = 2 THEN 'write'
        WHEN co.mode = 3 THEN 'admin'
        WHEN co.mode = 4 THEN 'owner'
        ELSE 'failed'
    END AS permission
FROM collaboration co
INNER JOIN repository r ON r.id = co.repo_id
INNER JOIN user uo ON uo.id = r.owner_id
INNER JOIN user u ON u.id = co.user_id;

Execution:

CONFIG_FILE=./app.yml go run ./cmd/collaborator/main.go
