Legacy voice data migrations are becoming one of the most expensive and under-estimated risks facing regulated organisations. Outdated call recording systems may appear harmless, but when audits or regulatory checks expose weaknesses in metadata, encryption, or record retention, the damage can be both financial and reputational.
These issues often stem from ageing infrastructure, forgotten codecs, and unsupported systems that are difficult to manage or migrate safely, claims Wordwatch.
When a recorder reaches end-of-support, the immediate response is usually to migrate its data to a newer platform. Many assume this is a straightforward process of transferring files, re-keying encryption, and updating metadata. In reality, the complexity of voice data makes this far from simple. Unlike email, voice recordings depend on fragile components such as codecs, time-aligned metadata, encryption wrappers, and legal hold markers. These elements create technical challenges that most organisations only discover mid-migration—often too late to avoid costly compliance failures.
Migration projects fail for a host of reasons. Manual migrations, for instance, come with high consultancy and validation costs, and in a few years, the new system will likely reach end-of-support too, forcing yet another migration. The chain of custody can also break if files are re-encrypted or transcoded, which compromises evidentiary integrity—an immediate concern for regulators. Metadata drift adds another layer of risk, as the loss or corruption of contextual information can render recordings untraceable, leading to compliance breaches.
Technical inefficiencies further compound these problems. Transcoding can dramatically inflate file sizes—sometimes by as much as 16 times—leading to soaring storage costs and slower data retrieval. Misconfigured migrations can also lose critical fields such as legal holds and retention policies, resulting in data being prematurely deleted. Once deleted, that data is irretrievable, creating a severe regulatory exposure. Human oversight adds another bottleneck, as compliance, IT, and legal teams often spend months validating results that provide little long-term business value. Even when everything seems to go right, valuable metadata such as user tags and annotations are often lost, reducing the overall usefulness of the data.
Recognising these pitfalls, leading regulated firms are moving away from the “lift-and-shift” approach. Instead of treating legacy compliance archives as liabilities, they’re beginning to view them as assets that can deliver business insight—provided they are governed intelligently.
Wordwatch offers a transformative alternative by eliminating the need for future migrations altogether. Its unified platform consolidates both legacy and live voice recordings from multiple vendors into a single compliant environment, without reformatting or moving data. The system retains each file in its original format, maintaining a verifiable audit trail and ensuring regulatory defensibility.
By preserving metadata, legal holds, and retention policies during ingestion, Wordwatch ensures that compliance rules remain intact. Automated validation and zero-touch ingestion reduce manual workloads while boosting confidence in governance processes. Moreover, the platform’s support for rich metadata enables advanced search, case management, and AI-powered surveillance—helping firms mitigate regulatory risk while unlocking new value from their communications data.
