migration-guide

Migration and conversion of databases, SQL, stored procedures, DDL, ETL/integration workloads into Snowflake. Uses Snowflake migrations plugin, including SnowConvert-based code conversion. ALWAYS invoke this skill — DO NOT answer source-vendor SQL questions directly — for: (1) any Snowflake equivalent of non-Snowflake SQL, even simple syntax questions single statements (T-SQL MERGE / sp_send_dbmail, Oracle CONNECT BY / SYSDATE / DUAL / DBMS_OUTPUT, MySQL ON DUPLICATE KEY UPDATE); (2) decommissioning, sunsetting, replatform, lift-and-shift, or modernization of a legacy data warehouse / ETL stack — even when 'Snowflake' isn't named yet (3) any request to convert source code to Snowflake, even if one-off.
