What is the best way to handle 4D multi-value fields when converting to .NET?▼

Handling 4D multi-value fields during a .NET migration requires specific schema conversion strategies to map them into relational structures. The migration process addresses these challenges directly alongside blob storage and date/time handling to ensure data integrity.

Can I convert 4D forms directly into Blazor components?▼

Yes, you can convert 4D forms into Blazor components. The migration process provides specific UI migration guidance and strategies for transforming legacy 4D form structures into modern Blazor UI components within the .NET 10 architecture.

How does data type mapping work when transferring 4D data to SQL Server 2022?▼

Data type mapping when transferring 4D data to SQL Server 2022 works by translating 4D specific types into compatible SQL Server formats during the data migration phase. This includes validation to ensure data integrity is maintained throughout the transfer.

Does this 4D to .NET migration process support cloud-native ERP systems?▼

Yes, the 4D to .NET migration process supports cloud-native ERP systems. It is designed to guide the migration of decades-old 4D-based ERP systems to modern cloud-native .NET 10 and SQL Server 2022 architectures from schema analysis to UI modernization.
