Cloud Migration & Modernization

Migrate from Legacy Tools with Zero Downtime

Transition from Splunk, legacy platforms, and on-premises infrastructure to modern observability without business disruption.

Fleet Management in OpenTelemtery

The Problem

Cloud Migration Creates Observability Gaps

Organizations modernizing their infrastructure face a critical challenge: maintaining visibility during the transition. Migrating from legacy tools like Splunk or on-premises monitoring platforms to cloud-native observability creates risks—data loss during cutover, performance degradation due to unfamiliar tooling, compliance violations from data residency changes, and business disruption if monitoring fails during migration.

The cloud migration challenge:

  • Business continuity risk: Switching observability platforms creates potential for monitoring gaps during critical transition periods
  • Vendor lock-in: Legacy platforms like Splunk make migration expensive and complex through proprietary data formats
  • Cost explosion: “Lift and shift” approaches to cloud often result in 2-3x increase in observability costs
  • Tool sprawl: Organizations add cloud-native tools without removing legacy systems, creating operational overhead
  • Hybrid complexity: Maintaining visibility across on-premises and cloud during multi-year migrations
  • Skills gap: Teams trained on legacy tools struggle with new cloud-native observability platforms

Failed migrations result in observability gaps that impact reliability, compliance violations, and cost overruns that undermine cloud business cases.

Our Solution

Risk-Free Migration with Parallel Operations

Apica enables zero-downtime migration from legacy observability platforms to modern, cost-efficient telemetry management. Our approach doesn’t force rip-and-replace—instead, we run parallel with existing tools during migration, providing safety net visibility while you transition at your own pace. Unlike traditional platforms, Apica optimizes your existing investments rather than replacing them, reducing migration risk and cost.

Built for migration success:

  • Parallel operation: Dual-ship telemetry to legacy and new platforms simultaneously during transition
  • Incremental migration: Move workload by workload, team by team at your own pace
  • Zero data loss: Never Block, Never Drop guarantee ensures complete visibility throughout migration
  • Cost optimization: Reduce overall observability spend 40% even while running parallel systems
  • Hybrid visibility: Unified platform for on-premises and cloud infrastructure during transition

The Apica advantage: We make migration safe, gradual, and economically beneficial—not a high-risk, big-bang event.

How It Works

Phased Migration Approach

Telemetry pipeline ensures business continuity during platform transitions.

Dual-Shipping for Safety

  • Send identical data to legacy platform (Splunk) and new destination simultaneously
  • Maintain full visibility in existing tools while validating new platform
  • Eliminate cutover risk—keep legacy running until confident in replacement
  • Support rollback if needed without data loss

Incremental Workload Migration

  • Migrate one service, application, or team at a time
  • Route different data sources to different destinations based on migration readiness
  • Maintain legacy integrations for unmigrated workloads
  • Reduce risk through gradual, controlled transition

Data Transformation for Compatibility

  • Transform data formats to match new platform requirements
  • Normalize telemetry from heterogeneous sources
  • Ensure downstream tools receive data in expected formats

Cost Control During Migration

  • Filter redundant data to avoid paying twice for same telemetry
  • Sample non-critical data during parallel operation to control costs
  • Intelligent routing ensures you don’t over-index in multiple expensive platforms

InstaStore™ provides safety net storage during platform transitions.

Migration Buffer

  • Store complete data history during migration for rollback capability
  • Infinite retention ensures no data loss during transition period
  • Instantly replay historical data to new platform without re-ingestion

Hybrid Query Support

  • Query data from both legacy and new platforms in unified interface
  • Maintain operational continuity for teams during learning curve
  • Historical analysis spanning pre- and post-migration periods

Cost-Efficient Parallel Operation

  • Avoid duplicate storage costs by using object storage as single source
  • Feed both legacy and new platforms from same data reservoir
  • Eliminate expensive parallel storage in multiple proprietary systems

Universal agent support minimizes instrumentation changes during migration.

Work with Existing Agents

  • Support for Splunk Universal Forwarder, legacy agents alongside modern collectors
  • No need to re-instrument applications during platform migration
  • Gradual agent replacement on your timeline, not vendor’s

OpenTelemetry Migration Path

  • Migrate to OpenTelemetry standard for vendor-neutral instrumentation
  • Instrument once, route anywhere—eliminate future migration pain
  • Support for gradual OpenTelemetry adoption alongside legacy instrumentation

Unified monitoring across on-premises and cloud during multi-year transitions.

Hybrid Infrastructure Monitoring

  • Single platform for legacy on-premises and cloud-native workloads
  • Consistent observability experience regardless of infrastructure location
  • Track migration progress with unified visibility

Team Enablement

  • Familiar interfaces reduce learning curve for teams trained on legacy tools
  • Gradual skill development as teams transition to cloud-native observability
  • Documentation and training for Splunk migration specifically

Common Migration Scenarios

Splunk to Modern Observability

Challenge: Splunk costs growing 200%+ annually; vendor lock-in prevents easy migration Apica 

Solution:

  • Dual-ship logs to Splunk and Apica Lake during transition
  • Reduce Splunk ingestion 50-70% through intelligent filtering
  • Migrate teams incrementally while maintaining Splunk for holdouts
  • Complete data ownership in open formats prevents future lock-in

Typical Results:

  • 50-70% immediate Splunk cost reduction
  • Zero business disruption during 6-12 month migration
  • Complete migration flexibility—keep Splunk as long as needed

On-Premises to Cloud

Challenge: Maintaining visibility across hybrid environment during multi-year cloud migration 

Apica Solution:

  • Unified platform for on-premises and cloud infrastructure
  • Route on-prem data through local Flow instances to cloud Lake
  • Hybrid dashboards showing both environments
  • Gradual decommissioning of on-prem monitoring as workloads migrate

Tool Consolidation

Challenge: 10+ monitoring tools creating operational overhead and cost

Apica Solution:

  • Flow routes telemetry to consolidated platform while maintaining legacy integrations
  • Migrate one tool at a time (APM first, then logs, then infrastructure)
  • Reduce tool count without forced big-bang consolidation
  • Optimize remaining tools through intelligent routing

The Result

Successful, Cost-Effective Migration

Migration Success Metrics

Organizations migrating with Apica achieve:

  • Zero downtime during platform transitions through parallel operation
  • 50-70% cost reduction compared to legacy platforms (especially Splunk)
