MSSQL to Snowflake Migration
Migrate your Microsoft SQL Server databases to Snowflake cloud data warehouse with automated schema conversion and data validation.
Why Migrate from MSSQL to Snowflake?
Unlimited Scalability
Scale compute and storage independently. No more capacity planning or hardware upgrades.
Pay Per Use
Only pay for the compute time you actually use. Pause warehouses when not needed.
Concurrent Users
Support unlimited concurrent queries without performance degradation.
Zero Maintenance
No patching, no backups to manage, no index tuning. Focus on your data, not infrastructure.
Data Type Mappings
| MSSQL Type | Snowflake Type | Notes |
|---|---|---|
| INT, BIGINT, SMALLINT | NUMBER | Direct mapping |
| VARCHAR, NVARCHAR | VARCHAR | UTF-8 encoding |
| DATETIME, DATETIME2 | TIMESTAMP_NTZ | Nanosecond precision |
| DECIMAL, NUMERIC | NUMBER(p,s) | Precision preserved |
| BIT | BOOLEAN | Direct mapping |
| UNIQUEIDENTIFIER | VARCHAR(36) | Stored as string |
Migration Process
Schema Analysis
Connect to your MSSQL database and analyze tables, columns, indexes, and constraints.
Risk Assessment
Identify data type incompatibilities, unsupported features, and potential data loss risks.
DDL Generation
Generate Snowflake-compatible CREATE TABLE statements with proper data types.
Data Transfer
Bulk load data using optimized methods with progress tracking and error handling.
Validation
Compare row counts, checksums, and sample data to ensure data integrity.
