GitLab Migrations

Moving to GitLab couldn't be easier.

From GitHub, Bitbucket, Azure DevOps, or SVN — OTTRA handles the full migration. History preserved. Pipelines rebuilt. Team ready.

Migrations delivered across Europe for teams of 30 to 200+ engineers. Every commit, branch, and tag preserved.

No commitment. Just a conversation. We reply within one working day.

Migrations fail for two reasons. The technical side isn't done properly. Or the team never buys in. Usually both.

Pipelines ported as-is instead of rebuilt
Commit history truncated or lost
Security scanning skipped and never revisited
Engineers handed a platform they've never been trained on
The sceptical team that keeps pushing to the old repo

OTTRA handles all of it.

A familiar situation

Three platforms. No single source of truth.

A leading defence organisation was running repositories across three separate platforms — GitLab, GitHub, and Bitbucket. CI/CD pipelines varied across all three. Build jobs were running on employee home computers and personal devices. For an organisation operating under NIST compliance requirements, this wasn't just inefficient — it was untenable.

OTTRA consolidated everything into a single self-managed GitLab Ultimate instance on Azure, rebuilt CI/CD infrastructure on a centralised Kubernetes cluster, and embedded security scanning and compliance controls into every pipeline from the ground up. Every repository migrated. Full commit history preserved. Build execution moved from personal devices to auditable, containerised infrastructure.

The organisation now has a platform built for the demands of a regulated defence environment — secure, auditable, and ready to scale.

The result

3 → 1 Platforms consolidated

From three disconnected platforms to a single, auditable GitLab instance with centralised CI/CD.

100% History preserved

Every commit, branch, and tag migrated intact. Nothing lost.

Full repository history preserved

Every commit, branch, and tag migrated intact. No truncated history. No fresh starts.

CI/CD pipelines rebuilt natively in GitLab

Not hacked across from GitHub Actions or Azure DevOps. Proper GitLab pipelines your team can own and maintain.

Security scanning enabled from day one

SAST, dependency scanning, and secret detection embedded into every repository before handover.

A team that's productive on GitLab immediately

SSO configured, access controls set, and your engineers trained so nobody's still pushing to the old platform a month later.

Discovery and planning

We map your current platform — repositories, pipelines, integrations, access controls, and team structure. Then we build a migration plan with a rollback strategy before anything moves.

Migration and rebuild

Repositories migrated with full history. CI/CD pipelines rebuilt natively in GitLab. SSO, group structures, and security scanning configured. Nothing is ported as-is — everything is built properly for the new platform.

Training and handover

Your team is trained on GitLab workflows before the old platform is decommissioned. Engineers are productive from day one. No lingering dependencies on the previous tool.
