Upgrade Entra Connect Sync before April 7, 2025

⏰ 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
