Actionable 90-day release checklist for engineering leaders consolidating acquired AI platforms into CI/CD, compliance, and distribution pipelines.

Hook: You just closed an AI platform acquisition — now every release is high risk

Consolidating an acquired AI platform into your engineering ecosystem is one of the highest-leverage and highest-risk moves an engineering leader can make. Pain points are familiar: mismatched CI/CD pipelines, brittle artifact distribution, opaque model provenance, and the extra burden of FedRAMP or other government compliance. In 2026, with supply-chain security expectations rising and AI-specific compliance guidance maturing, a sloppy migration costs money, mission access, and reputation.

This guide is an actionable release management checklist for engineering leaders consolidating acquired AI platforms (for example, a FedRAMP-approved AI platform like the one recently acquired by BigBear.ai) into your CI/CD, compliance, and distribution pipelines. It is biased toward government-facing teams and large organizations who must meet stringent controls while keeping developer velocity high.

Executive summary: top actions in the first 90 days

Days 0–30: Inventory, boundary definition, SBOM and SBOM of models, short-term isolation, and baseline tests.
Days 30–60: Standardize builds, add provenance and signatures, integrate artifact registry, and run compliance gap remediation (FedRAMP SSP updates, control mapping).
Days 60–90: Migrate CI/CD, enable policy-as-code checks, validate performance and security at scale, and cutover with canary/blue-green deployments and rollback plans.

Pre-migration assessment: what you must capture before changing anything

Before you touch pipelines, get a baseline. A quick but complete assessment reduces rework.

Critical inventory checklist

All source repositories and access controls (git origin, branch protection rules, MFA status).
All build artifacts and registries (container images, wheels, jars, model files, datasets).
Existing CI/CD flows and triggers (GitHub Actions, GitLab, Jenkins, Azure DevOps, Tekton).
Compliance posture: FedRAMP boundary, SSP, POA&M, ATO status, continuous monitoring tooling.
Third-party dependencies and licenses (generate SBOMs now).
Secrets and credentials management mapping (vaults, cloud KMS, IAM roles).
Operational runbooks and incident response playbooks.

Lightweight commands to produce rapid inventory results:

    # list repos for a GitHub org
    gh repo list my-acquired-org --limit 100

    # generate a SBOM for a repository or container image using syft
    syft dir:./acquired-repo -o cyclonedx-json > acquired-sbom.cdx.json

    # list container images in a registry (example: OCI)
    skopeo list-tags docker://registry.acquired.example.com/acq-image

Mapping compliance and FedRAMP boundaries

When the acquired platform is FedRAMP-approved, you inherit both opportunity and constraints. The FedRAMP-approved status speeds mission access but also imposes a boundary and documentation you must respect while consolidating.

Identify the system boundary: what stays in the acquired environment versus what will live in your environment. Feed this into the SSP.
Update or create an integrated System Security Plan (SSP) that documents all changes, including new artifact stores, CI/CD flows, and monitoring agents.
Map required controls: continuous monitoring, incident response, configuration management, and change control. Track these in your POA&M.
Plan for an ATO re-validation or FedRAMP package update if you modify the boundary or introduce new cloud providers.

CI/CD integration: standardize builds, enable reproducible artifacts, and add provenance

The single biggest cause of post-acquisition outages is inconsistent build inputs and unverified artifacts. In 2026 the accepted practice is to require reproducible builds plus cryptographic provenance before pushing artifacts to production.

Checklist for build standardization

Adopt a canonical build system or define a compatibility layer (e.g., adopt GitHub Actions or Tekton across both orgs).
Introduce build catalogs and a single artifact registry (or a federated registry with replication and RBAC).
Mandate SBOM generation and SLSA-style attestations for every build.
Sign every artifact with a centralized key-management process ( cosign / sigstore stacks are preferred in 2026).
Preserve build logs and provenance in an immutable store with audit logging.

Example GitHub Actions workflow snippet to build, create SBOM, sign, and publish an OCI image:

name: build-and-publish
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Build image
        run: |
          DOCKER_BUILDKIT=1 docker build -t registry.example.com/acq/app:${{ github.sha }} .
      - name: Create SBOM
        run: |
          syft registry:registry.example.com/acq/app:${{ github.sha }} -o cyclonedx-json > sbom.json
      - name: Sign image
        run: |
          COSIGN_PASSWORD=$COSIGN_PW cosign sign --key $COSIGN_KEY registry.example.com/acq/app:${{ github.sha }}
      - name: Push SBOM and attestation
        run: |
          curl -X PUT -H 'Content-Type: application/json' --data @sbom.json https://artifact-store.example.com/sboms/${{ github.sha }}

Artifact distribution and global performance

Merging artifact distribution means guaranteeing global availability and low latency for downloads. In 2026, expect business lines to demand a CDN-backed artifact distribution, geo-replication, and secure caching.

Consolidate registries where possible; use caching proxies for legacy registries.
Enable replication zones and TTLs for artifacts; verify integrity after replication (checksum verification).
Apply fine-grained RBAC and signed URLs for downloads in government environments.
Monitor download latency and cache-hit metrics as release KPIs.

Security and supply-chain controls

Your acquisition will face intense scrutiny on supply-chain controls. By 2026, SLSA attestations, SBOMs, and verifiable signatures are expected baseline controls for any government-facing AI product.

Minimum supply-chain checklist

SBOMs for every artifact and model file.
SLSA level 3+ attestations or equivalent provenance records.
End-to-end signing with keys under centralized KMS and rotation policy.
Policy-as-code gates to prevent unsigned or unproven artifacts from deploying (Open Policy Agent or native CI checks).
Runtime verification: verify artifact signatures at deploy time and enforce image allowlists.

Example OPA rego snippet to block unsigned images (simple illustration):

package kubernetes.admission

denied[msg] {
  input.request.object.spec.containers[_].image == img
  not is_signed(img)
  msg = sprintf("image not signed: %s", [img])
}

# Placeholder function to represent signature check
is_signed(img) {
  # In practice, call an external attestation service
  true
}

Data and model migration: provenance, privacy, and validation

Data and model migration is where AI acquisitions frequently stall. Models are not only code — they embody training data, hyperparameters, and often PII responsibilities.

Catalog all model artifacts and their training datasets. Create a model registry entry for each model with a model card.
Confirm data classification and any residual PII. Apply encryption-in-transit and at-rest; use double-check migration patterns and logging.
Validate model behavior with a standardized test harness: functional tests, bias and fairness checks, and performance regression suites.
Define a rollback plan that includes both model and data versions. Keep the acquired environment available as a fallback for 30–90 days.

Model validation checklist

Re-run unit and integration tests against the model in your environment.
Run synthetic production traffic and compare latencies and outputs to recorded baselines.
Run explainability and fairness tests; preserve artifacts for audits.
Document retraining triggers and CI hooks for training pipelines.

Operationalization: deployment patterns, rollout, and rollback

Manage risk with progressive rollout strategies and strong observability.

Use canary or blue/green deployments for any service or model cutover.
Automate rollback triggers: SLO breaches, increased error rates, or failed integrity checks.
Ensure distributed tracing and model inference logging are enabled for effective debugging.
Keep the old artifact registry accessible behind strict access controls until the cutover window closes.

Governance, roles, and training

Clear ownership prevents the "who broke it" argument. Define a RACI and run short focused training for the teams touching the new platform.

R: Release engineers, platform SREs. A: Head of Engineering or CTO. C: Security and Compliance. I: Product Owners and Program Managers.
Run 1-day workshops on new pipelines, provenance requirements, and artifact flows.
Create simple runbooks for emergency rollback, key rotation, and incident reporting tailored to FedRAMP requirements.

90-day tactical checklist (detailed)

Day 0–7: Freeze non-critical changes in the acquired environment. Snapshot existing SSP and POA&M.
Day 7–14: Run SBOM and vulnerability scans across all repos and container images. Tag high-risk items.
Day 15–30: Define integration boundary and update SSP. Stand up audit logging to a central collector.
Day 30–45: Implement build standardization, SBOM generation, and artifact signing in CI pipelines.
Day 45–60: Integrate artifacts into the canonical registry and enable geo-replication and CDN caching.
- Run performance tests and tune caching TTLs.
Day 60–75: Add policy-as-code gates and pre-deploy checks; validate SLSA attestations and signatures.
Day 75–90: Execute staged cutover with canaries, monitor SLOs, and complete SSP updates and any required audits.

Example consolidation story: a hypothetical BigBear.ai-style migration

Consider a hypothetical: your company acquires a FedRAMP-approved AI platform that includes compute, model registry, and an artifact store. The platform is vertically integrated and optimized for government workloads, but your enterprise runs a separate CI/CD and global artifact distribution layer.

Steps taken in the example: inventory and SBOM first, followed by a parallel build path so both original and standardized pipelines co-exist. The team introduced cosign signing and SLSA-style attestations, used a federated artifact registry with strict RBAC, and ran a 2-week canary traffic shift for model serving. The result: reduced release friction, maintained FedRAMP boundary integrity, and lowered developer onboarding time for the acquired codebase by 60%.

This example mirrors real-world lessons emerging in late 2025 and early 2026: teams that invest early in provenance and policy-as-code avoid audits and regain velocity faster.

Advanced strategies and 2026 trends to exploit

Confidential compute and verifiable compute: Late 2025–2026 saw wider cloud support for confidential VM and enclave-backed attestation. Use these for sensitive model retraining or inference for government workloads; build these into your cloud-native strategy.
Policy-as-code and continuous compliance: More orgs are embedding compliance gates directly into pipelines; this reduces manual audits and automates FedRAMP control checks.
Model provenance and model cards: Expect auditors to request model lineage, dataset lineage, and model cards that explain intended use and limitations.
Supply-chain regulation: Governments and large enterprises increasingly require SBOMs and provenance. Prioritize SLSA-style attestations.

Metrics to watch during and after consolidation

Release lead time for changes impacting the acquired platform.
Artifact verification rate (percentage of artifacts with valid provenance/signature).
Download latency and cache hit ratio for artifact downloads.
Number of POA&M items opened or closed during migration.
Time to rollback (MTTR) for deploy failures linked to the cutover.

Common pitfalls and how to avoid them

Pitfall: Rushing cutover without provenance — avoid by adding signing and verification early.
Fix: Implement attestation and signing in parallel with initial builds.
Pitfall: Assuming FedRAMP status transfers — it does not; boundary changes require SSP updates and may trigger re-authorization.
Fix: Engage compliance early and plan for SSP/ATO updates.
Pitfall: Data and model drift after migration.
Fix: Keep comprehensive test suites and production shadowing before cutover.

Actionable takeaways

Do an immediate inventory and generate SBOMs for code, containers, and models.
Define the FedRAMP boundary and update SSP before major architectural changes.
Make artifact signing, SBOMs, and attestation non-optional gates in CI.
Use progressive deployment and keep a tested rollback path for 90 days after cutover.
Track release and artifact metrics and feed them into your governance reviews.
