Splunk Cloud Migration

Zero-disruption migration from on-premises Splunk to Splunk Cloud, run by the team that runs your SOC.

We help organisations migrate from on-premises Splunk to Splunk Cloud with zero disruption to security operations, covering historical data migration, custom app and knowledge object compatibility, and phased cutover planning. For clients with data residency or hybrid requirements, we also offer Splunk hosted on Nexagate's own private cloud as a flexible alternative.

Our end-to-end migration is designed around your environment's complexity, compliance obligations and operational continuity, so your security visibility never drops during the transition. A phased cutover with parallel run and shadow stages eliminates coverage gaps, and post-migration validation confirms dashboards, correlation rules and detection use cases all work as intended. The migration is handled by the same team that runs your ongoing SOC, so there are no handoff gaps between project and operations.
