What is integration platform migration?
Integration platform migration is the controlled transfer of an organisation's integrations, APIs and event flows from a legacy integration platform to a new one. A migration covers three layers: the integration logic, the connectivity to source and target systems, and the operational controls around both.
A typical integration estate contains several types of asset. These include:
- Point-to-point and orchestrated integrations between applications such as SAP, Salesforce, Workday and Oracle.
- APIs exposed to internal teams, partners and customers.
- Message queues and event streams that move data asynchronously.
- Scheduled batch jobs and file transfers.
- Monitoring, alerting, error handling and audit logging.
A migration is complete when every in-scope integration runs on the new platform, the legacy platform is decommissioned, and the licence for the legacy platform ends.
Which integration platforms can be migrated to Workato?
Co Valere migrates 4 main integration platforms to Workato: TIBCO, MuleSoft, webMethods and Boomi. Co Valere also migrates older enterprise service buses, such as Oracle SOA Suite, IBM Integration Bus and IBM App Connect Enterprise.
Each platform has a different migration pattern. The patterns are:
- TIBCO. BusinessWorks processes become Workato recipes, and EMS queues and topics move to Workato Event Streams.
- MuleSoft. Mule applications and DataWeave transformations become recipes, and Anypoint APIs move to the Workato API Platform.
- webMethods. Integration Server services and Trading Networks partner flows become recipes and B2B integrations. IBM acquired webMethods from Software AG in 2024, according to IBM.
- Boomi. Boomi processes and maps become recipes, and Boomi Atoms are replaced by Workato on-prem agents where systems sit behind the firewall.
Custom-coded integrations also migrate. Scripts, scheduled jobs and file transfers become recipes with the same monitoring and error handling as every other integration.
Why are enterprises migrating off TIBCO, MuleSoft, webMethods and Boomi?
Enterprises migrate off TIBCO, MuleSoft, webMethods and Boomi for 4 main reasons: support deadlines, licensing cost, skills scarcity and the need for AI-ready integration. Each reason applies to the platforms differently.
The first reason is support deadlines. TIBCO ActiveMatrix BusinessWorks 5.14 reached end of support on 31 March 2026, and BusinessWorks 5.15 reaches end of support on 30 November 2026, according to TIBCO's published support policy. Organisations on these versions must upgrade, pay for extended support or migrate.
The second reason is licensing cost. TIBCO has been part of Cloud Software Group since 2022, alongside Citrix. Processor-based and vCore-based licensing models tie integration cost to infrastructure size rather than business value. Workato licenses by usage, according to Workato documentation. Usage pricing aligns cost with the number of recipes and tasks the business runs.
The third reason is skills scarcity. TIBCO BusinessWorks, webMethods Integration Server and MuleSoft Anypoint each require specialist developers. Workato recipes use a low-code model that integration teams and business technologists can both maintain.
The fourth reason is AI readiness. AI agents need governed, real-time access to enterprise systems through APIs, events and tools. Workato has been named a Leader in the Gartner Magic Quadrant for iPaaS for 8 consecutive years, according to Workato's March 2026 announcement.
How long does an integration migration take?
An integration migration takes 2 to 18 months. Co Valere's in-house accelerators and migration tooling shorten migrations within this range. Integration count drives duration more than any other factor, followed by the number of connected systems and the quality of existing documentation.
The table below shows typical durations by estate size:
| Estate size | Integrations | Duration | Two-week sprints |
|---|---|---|---|
| Small | Fewer than 50 | 8 to 16 weeks | 4 to 8 |
| Medium | 50 to 200 | 3 to 9 months | 6 to 18 |
| Large | More than 200 | 9 to 18 months, in waves | 18 to 36 |
Rationalisation shortens migrations. Co Valere reduced one manufacturer's active integrations by 60% before and during rebuild, which reduced the number of integrations that needed migrating. Large estates migrate in waves of 20 to 50 integrations, so each wave delivers value before the next begins.
How much does an iPaaS migration cost?
An iPaaS migration costs between £60,000 and £1.5 million (about $75,000 to $1.9 million), depending on estate size, complexity and the degree of rationalisation. The cost covers assessment, rebuild, testing, cutover and parallel running; platform licences are additional.
The table below shows typical services cost ranges by estate size:
| Estate size | Integrations | GBP | USD |
|---|---|---|---|
| Small | Fewer than 50 | £60,000 to £150,000 | $75,000 to $190,000 |
| Medium | 50 to 200 | £150,000 to £500,000 | $190,000 to $630,000 |
| Large | More than 200 | £500,000 to £1.5 million | $630,000 to $1.9 million |
Five factors drive migration cost. These are:
- Integration count and complexity, including custom code and transformation logic.
- Documentation quality, because undocumented integrations need reverse-engineering.
- Number of connected systems, especially on-premises systems that need secure agents.
- Testing scope, including regression testing against production data patterns.
- Parallel running, because both platforms run until cutover completes.
Migration cost is offset by retired legacy licences, infrastructure and specialist support contracts. The offset period is typically 6 to 24 months.
What are the stages of a migration?
An integration migration has 6 stages, grouped into the 3 phases of Co Valere's ACT (Accelerated Controlled Transformation) framework. Each stage has a defined output that the next stage depends on.
The 6 stages run in this order:
- Assess (Assess & Align). Inventory every integration, its systems, volumes, owners and business criticality.
- Map (Assess & Align). Map each legacy integration to its Workato design and decide whether to rebuild, consolidate or retire it.
- Rebuild (Construct & Coordinate). Build Workato recipes, connectors, APIs and event streams to agreed design standards.
- Test (Construct & Coordinate). Run functional, regression and performance tests against representative data.
- Cut over (Transition & Transform). Switch traffic in waves, with a rollback plan and parallel running for critical flows.
- Decommission (Transition & Transform). Retire legacy integrations, servers and licences, and close the migration.
Assessment and mapping usually take 10% to 20% of total migration effort. This early investment reduces surprise dependencies during rebuild and cutover.
What are the main risks of an integration migration?
An integration migration has 4 main risks: hidden dependencies, behaviour changes, business disruption and scope growth. Each risk has a specific control.
The table below pairs each risk with its control:
| Risk | Control |
|---|---|
| Hidden dependencies between integrations | Full inventory and dependency mapping during assessment |
| Behaviour changes after rebuild | Regression tests that compare legacy and Workato outputs on the same inputs |
| Business disruption at cutover | Wave-based cutover, parallel running and a tested rollback plan |
| Scope growth during rebuild | A rebuild, consolidate or retire decision for every integration before build starts |
Governance reduces all 4 risks. Co Valere applies design standards, peer review and an architecture decision log from the first wave to the last.
What happens after the migration?
After the migration, the integration team runs every integration on Workato under one set of design standards, monitoring and access controls. The legacy platform, its servers and its licences are retired.
Three changes follow the move to Workato. These are:
- New integrations take less time to build, because recipes reuse pre-built connectors. Co Valere's packaging manufacturer client now delivers new integrations 3 times faster.
- Business technologists can build and maintain simple recipes inside governance guardrails, which reduces the backlog on the central integration team.
- AI agents can use governed recipes and APIs as tools, which connects AI to live enterprise systems.
Co Valere offers managed support after cutover for organisations that want a partner to run the platform.
What if an organisation is not ready to migrate?
An organisation that is not ready to migrate can keep its current integration platform under Co Valere support and managed services. Co Valere supports TIBCO, MuleSoft, webMethods, Boomi and older enterprise service buses such as Oracle SOA Suite and IBM App Connect Enterprise.
Support and managed services cover 4 areas. These are:
- Day-to-day running, monitoring and incident response for existing integrations.
- Upgrades and patching, such as moving TIBCO BusinessWorks 5 estates to the 5.16.1 long-term support release.
- Changes and new integrations on the current platform while a migration is planned.
- A migration assessment built into the support engagement, so the organisation is ready to move when its renewal date or budget allows.
