SuiteScript 1.0 to 2.1 Migration Services
NetSuite SuiteScript 1.0 Deprecation Timeline
Plan your migration around Oracle's published release milestones
Oracle has announced a phased transition to SuiteScript 2.1, with legacy version support expected to be removed in NetSuite 2028.2. The milestones below distinguish reduced support from deployment restrictions and the final transition requirement.
| NetSuite Release | Published Change |
|---|---|
| 2026.2 | SuiteScript 2.1 becomes the standard for both new and existing scripts. |
| 2027.1 | SuiteScript 1.0 support narrows to critical issues. Other fixes require conversion to 2.1 first. |
| 2028.1 | New accounts cannot deploy 1.0 scripts; existing accounts still can. SuiteScript 2.0/2.x runs as 2.1 by default. |
| 2028.2 | All scripts, including existing customizations, must use SuiteScript 2.1. |

What This Means for Your Business
A legacy script may be responsible for invoice creation, order validation, inventory updates, or an integration your staff uses every day. Your migration plan should identify who owns each process and how the team will confirm it still works after conversion.
Allow time for undocumented dependencies, vendor coordination, and business-user testing. A script that runs without an error can still produce an unexpected transaction result.
Build Your Migration Plan with SixLakes
We can help define your conversion backlog, estimate the agreed scope, and coordinate testing and release windows around financial close, peak sales periods, and other operational constraints.
About Us
We plan migration work around the people, transactions, and integrations that depend on your existing scripts.
Why Choose SixLakes for Your Migration?
Get a clear view of what needs to change, how it will be validated, and what your administrators will need to support it after release.
Let's TalkA Prioritized Migration Backlog
We classify scripts by business impact, dependencies, source availability, and testing effort so you can plan work in manageable groups.
Business Behavior as the Baseline
We capture expected transaction results and process exceptions before conversion to give reviewers a practical basis for acceptance.
Clear Ownership and Scope
We identify who can approve changes and which third-party components require coordination with their publisher.
Documented Conversion Decisions
We explain API replacements, design changes, and configuration dependencies so the upgraded code can be maintained.
A Release Plan for Your Account
We align deployment windows, validation steps, and rollback decisions with your business calendar and support team.
Handover Beyond the Code
We provide the agreed documentation, test evidence, and follow-up support so your team understands what changed.
Our SuiteScript Migration Process
An agreed scope, documented test results, and a coordinated rollout
Inventory & Assessment
We review the scripts you want to migrate and identify the business processes they support.
- Active deployments, schedules, and execution contexts
- Shared libraries, integration dependencies, and code ownership
- Business criticality and source-code availability
Deliverable: A script inventory with dependencies and assessment findings.
Migration Roadmap & Scope
We group the work into release phases and agree on the evidence needed to approve each one.
- Scripts to convert, redesign, or review for retirement
- Acceptance criteria and representative test data
- Delivery milestones, responsibilities, and release constraints
Deliverable: An agreed migration backlog and scope-based estimate.
SuiteScript 1.0 Code Conversion
We adapt the legacy implementation to the SuiteScript 2.1 module structure.
- API mapping and entry-point changes
- Dependency, search, and record-operation reviews
- Alternative designs where a direct API equivalent is unavailable
Deliverable: Converted source code with documented design decisions.
Regression Testing & Acceptance
We compare the converted scripts with agreed business results in your sandbox.
- Normal transactions, exceptions, and supported user roles
- Integration responses and scheduled processing
- Representative volumes and business-owner review
Deliverable: Test results, resolved findings, and release approval criteria.
Staged Production Rollout
We coordinate deployment around your operational schedule and the dependencies between scripts.
- Deployment and configuration checklist
- Rollback steps and decision owners
- Production verification and initial monitoring
Deliverable: A controlled release with documented verification.
Handover & Follow-Up Support
We transfer the agreed documentation and help investigate issues discovered after deployment.
- Source code and deployment notes
- Administrator troubleshooting and ownership handover
- Follow-up fixes and remaining migration priorities
Deliverable: A maintainable solution and a clear support handover.
Plan Your SuiteScript 1.0 to 2.1 Transition
Understand the conversion work, scope, and information needed to get started
What Changes During Conversion?
SuiteScript 1.0 uses global functions, while SuiteScript 2.1 uses modules and methods. Migration involves reviewing script types, entry points, and dependencies. Some legacy functions have no direct equivalent and need a different implementation.
We assess those differences before committing to a conversion approach. The test plan checks the business behavior your team expects in each relevant execution context.
What Determines Scope and Timing?
Effort depends on script complexity, shared libraries, integrations, available test data, and the number of processes that need business-owner validation. Third-party code may require its publisher's involvement.
To begin, share a script list if available, the processes affected, known issues, and any release constraints. We can start with a focused assessment or a small conversion phase before scoping a wider migration.

Frequently Asked Questions
Common questions about planning and delivering a SuiteScript migration.
Can SuiteScript 1.0 be migrated directly to 2.1?
Yes, through code conversion. We review the script structure, entry points, dependencies, and API calls, then test the converted implementation. Changing a version label alone does not convert a SuiteScript 1.0 script.
What do we receive from a migration assessment?
The agreed assessment can include a script inventory, dependency findings, compatibility concerns, a prioritized backlog, and a proposed test and release approach. We confirm the deliverables with you before work begins.
Can you migrate only our most important scripts first?
Yes. We can scope a single script or a release group. We review shared dependencies before deciding which scripts can move together and which can be handled separately.
How much does a SuiteScript migration cost and how long does it take?
We estimate after reviewing the scripts and testing requirements. Complexity, source-code quality, integrations, test data, and approval availability all affect effort. A focused assessment can help define a realistic scope and sequence.
Can you migrate scripts supplied by a third-party vendor?
We first confirm code access, ownership, and the supported update path. Some components require the publisher to provide an upgrade. We can help identify those dependencies and coordinate the migration plan with your team.
How do you reduce disruption during deployment?
We plan sandbox regression testing, business-owner acceptance, staged releases, and rollback steps. After deployment, we verify the agreed production behavior and provide the follow-up support included in your scope.
