Upgrade Entra Connect Sync before April 7, 2025

Microsoft has released important updates for Entra Connect Sync, AD FS and PingFederate. These updates contain critical back-end service changes that you must implement by April 7, 2025. Are you not doing this? Then you run the risk of failures in your hybrid identity scenarios 😱.

From Google Drive to Microsoft 365: prepared for NIS2!

⏰ What happens if you don’t upgrade on time?

❌ Authentication through the wizard will fail (think staging mode, changing login methods, etc.).
❌ AD FS configuration via wizard no longer works
❌ PingFederate configuration via wizard no longer works

✅ What does continue to function?

🔄 Synchronization between on-prem AD and Entra ID remains active
📦 Upgrading after April 7 remains possible (but preferably before of course!)

🔧 Minimal versions to stay safe

🌐 Commercial clouds: Version 2.4.18.0 or higher
🏛️ Government clouds and other non-commercial variants: Version 2.4.21.0 or higher

Note that these versions require TLS 1.2 and .NET Framework 4.7.2

🤖 Automatic upgrades?

Good news! Microsoft performs automatic upgrades whenever possible. Just make sure:

Your version is at least 2.3.20.0
The auto-upgrade function is set properly

🌥️ Consider Microsoft Entra Cloud Sync

Want a future-proof solution? Then Cloud Sync is worth considering:

💡 Cloud-native synchronization management
⚙️ Less infrastructure
📈 Better scalability and flexibility

Use the evaluation wizard to determine if Cloud Sync is right for your organization.

📌 Action items in a row:

✅ Upgrade to the appropriate version by April 7, 2025
🔍 Check if your environment is compliant (TLS/.NET)
🤔 Consider switching to Cloud Sync for maximum flexibility

🔒 Is your hybrid identity management future-proof yet?
Microsoft’s updates offer more security as well as Cloud Sync capabilities.
