2,200 Systems Decommissioned Without Compromising Legal Holds

2,200 Systems Decommissioned Without Compromising Legal Holds

After acquiring thousands of legacy systems containing data under legal hold, a global financial institution needed to retire 2,200 repositories, some exceeding 1PB, without risking compliance. Lighthouse stepped in to bridge Legal and IT, validating preservation plans, creating a detailed playbook, setting documentation standards, and conducting regular reviews. Their framework ensured immutability, long-term access, and defensible preservation across jurisdictions. The client consolidated all work under Lighthouse, extending the project to 30 months. This approach reduced costs, maintained legal hold compliance, improved coordination, mitigated regulatory risk, and delivered long-term operational savings.
