Vlocity to OmniStudio Migration: What It Actually Takes in 2026

SoftShala Team Apr 2026 14 min read

If your organisation is still running on Vlocity — now officially called OmniStudio — you're not alone. Thousands of enterprises made the Vlocity bet before Salesforce acquired it in 2020, and many are still running the original stack today. The question isn't whether to migrate. It's when, and how to do it without breaking production.

At SoftShala, OmniStudio migration is one of our core specialisations. We've executed full Vlocity-to-OmniStudio migrations for FMCG, telecom, and financial services clients. Here's the honest breakdown of what changes, what stays the same, and what you need to watch out for.

What Is the Difference Between Vlocity and OmniStudio?

Technically, OmniStudio is Vlocity — rebranded and replatformed by Salesforce after the $1.33B acquisition. But the rebrand came with meaningful architectural changes:

• DataRaptors are now called DataRaptors — same name, but the runtime engine has changed significantly in how it handles JSON transformations
• OmniScripts replaced FlexCard-based flows in many patterns; the scripting syntax has evolved
• Integration Procedures have tighter governor limit enforcement in OmniStudio vs. legacy Vlocity
• FlexCards now have native LWC (Lightning Web Component) compilation, which changes how custom components embed
• Namespacing — this is the big one. Vlocity used vlocity_ namespacing. OmniStudio uses omnistudio namespacing. Every metadata reference has to be updated.

The Migration Process: What It Actually Looks Like

Phase 1: Inventory and Assessment (1–2 Weeks)

Before touching anything, you need a complete inventory. This means cataloguing every OmniScript, DataRaptor, Integration Procedure, FlexCard, and Vlocity Action in your org — documenting what it does, what it calls, and what depends on it. We use automated scanning tools combined with manual review. Skipping this phase is the fastest way to a failed migration.

Phase 2: Dependency Mapping

Once you have your inventory, you map the dependency graph. OmniScript A calls DataRaptor B, which calls Integration Procedure C, which calls an Apex class D. If you migrate them in the wrong order, or miss a dependency, you break the chain. We typically find 20–40% more dependencies than clients expect when they come to us.

Phase 3: Sandbox Migration and Testing

Never migrate directly to production. Build a full OmniStudio environment in a dedicated sandbox, execute the migration in dependency order, and run your full regression suite. For complex orgs, this phase typically takes 3–6 weeks.

Phase 4: Performance Validation

OmniStudio has stricter SOQL and CPU governor limits than Vlocity in some execution contexts. DataRaptors that ran fine on Vlocity may hit limits on OmniStudio due to tighter enforcement. We always run performance benchmarks in sandbox before production cutover.

Common Migration Failures (And How We Avoid Them)

• Missed namespace references — We run automated scans on all metadata XML before and after migration
• DataRaptor JSON schema drift — We validate every DataRaptor's input/output schema against the records it's actually processing
• Custom LWC conflicts — Any custom Lightning Web Components embedded in FlexCards need to be re-validated against OmniStudio's LWC runtime
• Integration Procedure timeout increases — Governor limits are tighter; we profile every IP's execution time

Timeline and Cost Reality

For a mid-complexity org (50–150 OmniStudio components), a well-executed migration takes 8–14 weeks from assessment to production go-live. For enterprise orgs with 300+ components, 16–24 weeks is realistic. Anyone telling you they can migrate 200+ components in under 6 weeks is cutting corners somewhere.

Should You Migrate Now or Wait?

Vlocity (the original platform) is in maintenance mode. Salesforce's active development is entirely focused on OmniStudio. New features, AI capabilities, and Consumer Goods Cloud enhancements are being built for OmniStudio only. If you're planning to stay on Salesforce for the next 3+ years, migration isn't optional — it's a matter of when.

Our recommendation: start your assessment now, even if you plan to execute the migration in 6–12 months. The assessment gives you a clear picture of scope, risk, and timeline so you can plan properly.
