# Bulk-migrate every GitLab project into Forgejo with full data

# (code, issues, merge requests, labels, milestones, releases, wiki).

# Usage:
|
|
# export GITLAB_URL=https://gitlab.nasarek.dev
|
|
# export GITLAB_TOKEN=glpat-xxxxxxxx # scopes: read_api, read_repository
|
|
# export FORGEJO_URL=https://git.nasarek.dev
|
|
# export FORGEJO_TOKEN=xxxxxxxx # Forgejo app token, repo + org scope
|
|
# export FORGEJO_OWNER=root # target user/org that will own the repos
|
