Migrating ~100 SSIS Packages to Azure: Acceleration Strategies & ADF vs. Fabric Guidance

For roughly 100 packages, I would not choose a blanket rewrite first. Microsoft’s SSIS migration guidance starts with assessment, then migration, because dependencies and unsupported components determine the economical path. Inventory package storage, SQL Agent schedules, connection managers, custom components, file shares, and protection levels. Run the Azure-enabled SSIS assessment in SSDT across the portfolio, classify blockers, and test a representative complex package on Azure-SSIS Integration Runtime connected to SQL Managed Instance. Lift and shift compatible packages first; rewrite only where blockers or redesign justify it. No supported converter reliably turns arbitrary SSIS control and data flows into ADF or Fabric pipelines. Fabric Data Factory is Microsoft’s recommended starting point for new integration work, but that does not make ADF SSIS-IR an invalid migration target. Use source control, parameterization, Key Vault, performance tests, and scheduled IR start/stop.
