Snowflake Migration · Derby
Snowflake Migration in Derby
Migrating Derby organisations onto Snowflake, where the temptation is to recreate the warehouse you had. Much of an existing schema exists to work around the old platform's limits — aggregate tables built because queries were slow, extracts created because concurrency was constrained — and carrying those forward means paying for a new platform to behave like the old one.
Why this comes up
The problem
The migration plan reproduces every aggregate table and nightly extract that existed to compensate for the previous system.
What you get
What we deliver
- Existing structures assessed for whether they solve a problem that still exists
- Workarounds for old platform limits identified and dropped deliberately
- Historic data migrated according to what is genuinely queried
- Transformations rebuilt rather than translated where the old approach was shaped by constraints
- Access model redesigned, since the previous one reflected different mechanics
- Parallel running with reconciliation before the old platform is retired

Working in Derby
East Midlands
Derby is an engineering city — aerospace, rail and automotive supply chains — so the work here skews toward integration with existing plant systems, quality and compliance workflows, and reporting that has to stand up to audit.
Most work here involves connecting shop-floor and plant systems to reporting the rest of the business can actually read, plus quality and compliance workflows that have to survive an audit.

Snowflake Migration in Derby — common questions
- Why not lift and shift?
- Because you inherit the compromises. Pre-aggregated tables, scheduled extracts and denormalised copies exist because the old platform could not answer the question directly — recreating them means the new platform never gets to demonstrate that it can.
- How much history should move?
- What is queried, plus what you are required to keep. Storage is inexpensive and migration effort is not, so bringing decades of detail that nobody has queried since it was written is cost without a corresponding use.
- What about existing transformations?
- Review them rather than translating. Logic written for a platform with different performance characteristics is frequently structured around avoiding operations that are now trivial, and rebuilding it produces something simpler as well as faster.
- Is parallel running necessary?
- For at least one full reporting cycle. Numbers must reconcile between old and new before anyone decommissions anything, and a month-end comparison finds the discrepancies that daily checks pass over. It also gives the finance and reporting teams a period to build confidence in figures they will shortly have no way of checking against anything.
- Do you work with businesses across Derbyshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Derby and the surrounding Derbyshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derby businesses do you usually work with?
- Most work here involves connecting shop-floor and plant systems to reporting the rest of the business can actually read, plus quality and compliance workflows that have to survive an audit. Beyond that we work across Advanced Manufacturing, Aerospace, Rail Engineering, Automotive and Logistics.
- Do you cover the areas around Derby?
- Yes — we work throughout East Midlands, including Nottingham, Leicester, Loughborough, Birmingham. Derby is an urban area of roughly 260,000+, and we take on work across the wider Derbyshire region rather than the city boundary alone.
