Migrations & Modernisation

Migrations that are worth doing, planned by people who used to sell them

Every vendor has a migration to sell you. We spent our careers building those services quotes, so we know what is in them, what is padding, and when the honest answer is to stay put and renegotiate. When a move is right, we plan it, cost it properly and lead it through to cutover, and we are not paid on the services that follow, so the recommendation is the real one.

What we migrate

Four kinds of move, each with its own trap

Storage migrations and consolidation

Moving between arrays, between vendors or between sites, and consolidating a fragmented estate onto fewer platforms without a performance cliff.

Leaving VMware, or staying well

Whether a Broadcom renewal justifies a move, and if it does, the migration to the platform that fits, sequenced so you are not over a barrel at the next renewal either.

Cloud, hybrid and repatriation

Moving workloads to cloud, back from it, or into a hybrid estate, on a business case built from your numbers rather than the launch deck.

Platform and tool modernisation

Retiring ageing platforms, disaggregating from converged stacks, and consolidating the tools around them, handed over service by service so nothing goes dark.

What you get

A migration you can hold us to

These are the moves we are asked to lead most often, not a boundary. If it is a migration or modernisation a high end IT consultancy would take on, we take it on, with the vendor side view of what it should cost. The decision to move sits with cloud and data centre advisory. The commercial side of the platform you are leaving sits with vendor renewal defence, and the platform you are buying with technology acquisition.

Proof

A fragmented storage estate, consolidated

45%smaller data centre footprint
38%better performance and throughput
30%+less power and cooling

A global enterprise ran ageing arrays from several top tier vendors, each bought on a different refresh cycle. We planned and led the consolidation onto fewer platforms, migrated the data without a performance cliff, and cut the cost of running the estate. Read the storage case study.

Questions

Frequently asked questions

How do you decide whether a migration is worth doing?

By costing it against the alternative of staying, on the same term. A migration is worth doing when the total cost of moving, including professional services, parallel running, retraining and the risk of disruption, is lower than the cost of staying and renegotiating. Often it is not, and C4C will say so, because we are not paid on the services that follow a migration.

What does a migration actually cost?

The licence or platform price is usually the smallest part. The costs most estimates miss are professional services, running the old and new platforms side by side, support overlap on the platform you are leaving, and the time your own teams spend. C4C builds the full figure before you commit, and the storage migration cost guide gives ranges by size and type.

Can you migrate us off VMware?

Yes, when the numbers say it is the right move. C4C first works the Broadcom renewal, because staying and renegotiating is often the cheaper outcome. When exit is genuinely right, we plan and lead the migration onto a platform that fits your workloads and structure it so you are not left exposed at the next renewal.

Do you do the migration yourselves or use partners?

C4C plans, leads and governs the migration. Hands on delivery is done by your own teams, a delivery partner of your choosing, or C4C with a partner where that is the right answer, and we say which. Where we supply or implement a partner platform, we say so on the page.

How do you avoid losing visibility or data during a move?

By handing over service by service rather than switching everything on one date. The old platform keeps running for each workload until the new one has been proven against a real test, then it is switched off. It is slower to start and much faster to finish, and nothing is ever running blind.
