Hi MD, Upgrading to Mendix 10.24 LTS is a solid move for long-term stability and performance. However, since your current application uses Email Templates, and the Email Template module is not available or supported in Mendix 10, you’ll need to migrate to the new Email Connector module before or during the upgrade.
Before Upgrading to Mendix 10.24 LTS
Migrate Email Templates
The old Email Template module is not supported in Mendix 10.
Replace it with the Email Connector module (from the Marketplace) while still on Mendix 9.x.
Rebuild email logic using Email Connector's microflows and custom templating if needed.
Update Marketplace Modules
Ensure all modules (Email Connector, Encryption, etc.) are updated to the latest versions before upgrading.
Clean Up Deprecated Features
Remove unused or deprecated modules like Email Template to prevent errors post-upgrade.
Backup Your App
Take a full backup of your project and database before upgrading.
Test Thoroughly
Re-test all email-related features using a test SMTP server (e.g., Mailtrap).
Verify dynamic data, formatting, and attachments.
Upgrade in a Branch
Perform the upgrade in a separate branch first to isolate and fix issues before merging too main.
I hope this one helps you! :)
