A One Woman Show of Migrating an Entire R&D SCM From Bitbucket Cloud to a Self-Hosted GitLab
summary
Solo migration of an entire R&D SCM from BitBucket Cloud to a self‑hosted GitLab completes in 1.5 months, with infrastructure built via GCP/GKE + Terraform and Helm release tweaks. Implementation includes repo imports (one large backend repo takes hours and is migrated over a weekend), Jenkins integration for CI, custom backups for DB plus Kubernetes secrets, dashboards and alerts, DNS/certificates, and docs/handovers for oncall teams. Many import bugs generate support tickets but the platform becomes production‑ready and maintainable.
