Power Automate flows vs. classic workflows
Organizations working with Dynamics 365 Customer Engagement face an important choice: continue working with the familiar classic workflows, or switch to Power Automate cloud flows? Microsoft has made it clear that the future lies with Power Automate, but that does not mean a transition is always straightforward or immediately necessary. In this article, we discuss the key differences, scenarios, and migration tips.
The fundamental difference
Classic workflows run synchronously or asynchronously within the Dynamics 365 environment itself. They are configured through the legacy workflow editor and are tightly coupled to the Dataverse data model. Power Automate cloud flows, on the other hand, run in the cloud as part of the broader Power Platform ecosystem. They offer hundreds of connectors to external systems, advanced conditional logic, and modern error handling.
The difference is comparable to that between a local macro in Excel and a full automation solution. Both have their place, but the capabilities of cloud flows surpass those of classic workflows in virtually every area.
When to choose cloud flows
Cloud flows are the right choice when your process requires interaction with systems outside Dynamics 365. Think of sending approval requests via Microsoft Teams, synchronizing data with external ERP systems, or calling REST APIs. Cloud flows also offer superior capabilities for parallel processing, loops, and advanced expressions.
- Integration scenarios: Connect Dynamics 365 with SharePoint, Teams, Outlook, and hundreds of other services without custom code.
- Complex business logic: Use conditions, switches, loops, and variables for advanced process flows.
- Approval processes: Build structured approval workflows with escalations and reminders.
- Scheduled tasks: Execute periodic tasks such as data cleanup, report generation, or batch processing.
When are classic workflows still relevant?
Despite the advantages of cloud flows, there are scenarios where classic workflows still play a role. Synchronous workflows that need to execute immediately when saving a record offer lower latency than cloud flows. Additionally, organizations with extensive existing workflow libraries do not always have the resources to migrate everything at once.
It is important to realize that Microsoft is actively investing in improving the real-time capabilities of Power Automate. The introduction of low-latency triggers and instant flows continues to narrow the performance gap.
The switch from classic workflows to Power Automate is not just a technical migration, but an opportunity to reconsider and optimize business processes. Organizations that seize this opportunity achieve an average of 40% more process efficiency.
Migration strategies from workflows to flows
A successful migration starts with a thorough inventory of your existing workflows. Categorize them based on complexity, business criticality, and dependencies. Start by migrating simple, non-critical workflows to gain experience, and then work toward more complex processes.
Microsoft offers tools to accelerate the migration process, including the workflow-to-flow converter in the Power Automate portal. While this tool does not handle all scenarios perfectly, it provides a solid starting point. At Breathbase, we use a phased approach that minimizes risks and ensures knowledge transfer to the internal team.
Best practices for a smooth transition
Document all your existing workflows before you start migrating. Use Dataverse solutions to organize and manage your flows. Test extensively in a sandbox environment before going to production. And invest in training for your team so that everyone becomes familiar with the new capabilities of Power Automate.
The future of process automation in the Microsoft ecosystem lies unambiguously with Power Automate. Organizations that start now with a thoughtful migration strategy position themselves optimally for the innovations to come.
