A migration guessed at from the outside runs over budget — hidden dependencies surface mid-cutover, not on paper. We audit your DB2 environment (schemas, SQL PL code, jobs, integrations, whether it’s z/OS, LUW, or IBM i) to size the real effort and flag risk early. You get a phased plan with milestones, rollback checkpoints, and a target platform recommendation, so the scope you’re quoted holds.

Moving years of DB2 data in one pass is where migrations stall — one bad batch can take production down with it. We convert your schema, map data types using SSMA for Db2, and migrate data in controlled, validated batches. Incremental replication keeps DB2 running throughout the move, so your business doesn’t pause while the data does, and every batch is verified first.

We rebuild SQL PL stored procedures, functions, and triggers as T-SQL — cursor logic, DECLARE HANDLER exception blocks, DB2’s global temporary tables — so converted code produces the same results as the original DB2 logic, rather than an approximation of it.

We update reporting and BI connections, ETL and batch job schedules, and application query logic. DB2 user roles and permissions are mapped to SQL Server’s security model, so nothing downstream breaks, and no behavior your business already depends on changes silently.

We baseline your current DB2 query and batch performance, then tune indexes, isolation levels, and execution plans on SQL Server, so batch jobs eating your overnight window finish faster, and reports that used to time out return.

Beyond checksum and row-count checks, we document every validation result in an auditable report for stakeholder sign-off. Rollback stays available throughout, so cutover is a scheduled decision and never a forced one.
