Modernizing Legacy IT: Quick Wins That Don’t Break Production

Legacy doesn’t mean bad—it means important. The trick is sequencing risk. Begin with observability (logs/metrics/traces), validate backups and recovery, and then strengthen identity (MFA, least privilege, conditional access). Use automation for repeatability, and carve out quick wins with measurable outcomes.

• Map dependencies before you move anything.
• Automate patches and configuration baselines.
• Pilot modernization on non-critical services, then iterate.
