GitHub Enterprise Migration: 2-Week Assessment
Deop Inc.
A two-week assessment that maps your repos, pipelines and access model, then returns a costed, sequenced GitHub Enterprise migration plan before you commit budget.
A two-week assessment that maps your repos, pipelines and access model, then returns a costed, sequenced GitHub Enterprise migration plan before you commit budget.
Migrating source control and CI/CD to GitHub Enterprise is rarely a tooling problem. It is a problem of untangling years of accumulated pipelines, permissions and undocumented build logic — and most teams discover the hard parts only after the migration is already underway.
This two-week assessment finds them first.
Deop maps your current estate, whatever it runs on today, and hands back a migration plan with the risks, sequencing and effort already costed.
Who this is for
Engineering and platform teams running Azure DevOps, GitLab, Bitbucket or self-hosted GitHub Enterprise Server who are planning a move to GitHub Enterprise Cloud and need a defensible plan before committing budget.
Week 1 — Discovery
- Repository inventory: size, history depth, Git LFS, submodules, binary artifacts
- Pipeline inventory: Azure Pipelines, GitLab CI, Jenkins and Bamboo definitions, each rated for conversion complexity
- Identity and access mapping: Entra ID groups, permission model, SSO and SCIM readiness
- Integration surface: artifact feeds, work item links, deployment targets, third-party tooling
- Constraints: compliance, sovereignty and data residency
Week 2 — Plan
- Target architecture: organisation and repository topology, teams, rulesets, environments
- Pipeline conversion strategy: what maps cleanly to GitHub Actions, what needs rebuilding, and what should be retired rather than migrated
- Runner strategy: GitHub-hosted versus self-hosted, with network and cost implications
- Security baseline: GitHub Advanced Security, secret scanning, dependency review, branch protection rulesets
- Sequenced migration waves with effort estimates and a cutover approach
- Risk register with mitigations
What you receive
- Migration assessment report with a disposition for every repository and pipeline
- Target-state architecture diagram
- Sequenced migration roadmap with effort estimates
- Risk register
- Executive readout session
Why Deop
We run GitHub Enterprise migrations as well as plan them — repository and pipeline conversion, identity and access design, runner topology and security baselines. The assessment is written by the engineers who would deliver the work, so the sequencing and effort estimates come from delivery experience rather than a template.
Source platforms supported: Azure DevOps, GitLab (SaaS and self-managed), Bitbucket (Cloud and Data Center), GitHub Enterprise Server, and legacy version control including Subversion on request.
