MIGRATION ASSESSMENT
Know what you’re migrating before the migration starts.
Before committing to a Snowflake or Databricks migration, understand the estate, complexity, dependencies, automation potential and migration risks.

WHAT WE ASSESS
Assess the whole estate—not just the schemas.
THE LEGACY ESTATE
10 AREAS ASSESSED
01
Databases and data
02
SQL and stored procedures
03
ETL and pipelines
04
CDC and ingestion
05
Schedulers and orchestration
06
Business rules
07
Data-quality logic
08
BI and downstream dependencies
09
Security and governance
10
Operational dependencies
The quality of the migration plan depends on how well the legacy estate is understood.
HOW DATACHECKS CLASSIFIES THE ESTATE
Decide what should happen to every part of the estate.
HIGHER AUTOMATION
MORE HUMAN JUDGMENT
AUTOMATE
Repeatable migration work that can be executed with high confidence.
MODERNIZE
Components that should move to a better target-native pattern.
REDESIGN
Complex workloads requiring architecture or engineering decisions.
RETIRE
Unused, redundant or unnecessary components that should not be migrated.
HUMAN REVIEW
Ambiguous or business-critical decisions requiring expert approval.
The assessment identifies where automation works—and where human judgment matters.
WHAT THE ASSESSMENT FINDS
Understand complexity before it becomes delivery risk.
Estate Size
How much is actually being migrated.
Dependencies
Upstream, downstream and cross-system relationships.
Complexity
Which workloads are straightforward and which are difficult.
Automation Potential
What can be automated using Datachecks and native migration tooling.
Migration Risks
Unsupported patterns, critical dependencies and business constraints.
Target Mapping
How the legacy estate should map to Snowflake or Databricks.
Migration Waves
Recommended sequencing based on dependencies and risk.
Delivery Scope
Clearer understanding of effort, team structure and execution approach.
WHAT THE CUSTOMER RECEIVES
A migration plan you can actually execute.
01
Estate Inventory
Complete inventory of relevant migration objects and workloads.
02
Dependency Map
Key relationships across systems and migration components.
03
Complexity Profile
Low, medium and high-complexity workload classification.
04
Automation Classification
Automate / Modernize / Redesign / Retire / Human Review.
05
Target Architecture Mapping
Recommended source-to-target migration approach.
06
Migration Waves
Recommended order of execution.
07
Risk Register
Known migration risks and likely blockers.
08
EXAMPLE ASSESSMENT OUTPUT

AI Agents
Estate discovery, profiling and classification executed at scale.
Native Migration Tooling
Source- and target-native analysis rather than generic scripts.
Migration Experts
Engineers validate the classification and own every judgment call.
Automation at scale. Human judgment where it matters.
WHAT HAPPENS NEXT
Assessment is the beginning—not the destination.
The assessment gives your team a clearer migration scope and provides the foundation for a Datachecks-led migration or an SI-led delivery program.

WHO SHOULD USE MIGRATION ASSESSMENT
Start with an assessment when…
01
You’re planning a Snowflake or Databricks migration.
02
The estate is poorly documented.
03
Migration effort and cost are unclear.
04
Your team needs confidence before committing to execution.
Know the estate. Scope the migration. Then execute.
Start with a structured assessment of your legacy estate, migration complexity and target architecture.
Give us the legacy estate. We’ll tell you exactly what it will take to migrate it.
