Best practices for integrating Adobe Experience Platform with Adobe Commerce in phased modernization projects

In ongoing modernization discussions, we are exploring how Adobe Experience Platform can be introduced gradually into existing Adobe Commerce ecosystems without requiring an immediate full migration.

Key areas we are analyzing:

• event streaming strategy
• customer/profile data synchronization
• App Builder extensibility patterns
• coexistence of legacy customizations with composable services
• operational impact during phased adoption

Would like to understand from the community:

• What integration patterns are working well?
• Any lessons learned from real implementations?
• Common challenges around scalability, governance, or data consistency?
• How are teams preparing for future ACCS adoption while still running PaaS?

Looking forward to hearing different implementation experiences and architectural approaches.
