Cloud Migration

Move your servers to the cloud with a planned, rehearsed migration

Migration runs as a project: inventory and dependencies are mapped, systems are grouped by how much downtime they tolerate, and each group is rehearsed on a copy first. What happens on migration night, and how to roll back if the plan fails, is written down in advance.

Service scope

  • Inventory and dependency report

    Resource needs, connections and downtime tolerance of every system are collected in a written report.

  • Sizing and cost forecast

    Current usage is measured to work out the CPU, memory and storage needed in the cloud, so the items that drive the monthly cost are visible up front.

  • Written migration plan

    Order, time windows, owners and communication steps sit in one written plan.

  • Rehearsal migration

    Critical systems move on a copy first and are validated, so the real move uses proven steps.

  • Rollback plan

    For every group, how to return to the old system if the plan fails is written in advance.

  • Validation and handover

    Every migrated system is checked against a list, with backup and monitoring in place from day one.

How to get started

  1. 1

    Inventory and dependency map

    Servers, applications, databases and the connections between them are mapped and documented.

  2. 2

    Grouping and plan

    Systems are grouped by downtime tolerance; order, windows and owners are agreed with the business units.

  3. 3

    Pilot migration

    A non-critical system and copies of critical systems move first, are validated with the application team, and downtime is measured.

  4. 4

    Planned migration

    Groups move in the agreed windows and every system is checked against a list; if the plan fails, the written rollback step is applied.

  5. 5

    Handover and monitoring

    Migrated systems are handed over with monitoring, backup and firewall rules, and the old environment is shut down with your approval.

Frequently asked questions

Can we lose data during the migration?
The old system stays running and is not shut down until validation is complete. If the plan fails, the written rollback step is applied and the system keeps running where it was.
How much downtime should we expect?
Downtime differs from system to system and is measured in the rehearsal migration. The measured figure is given to the business unit in writing before the move.
Do we have to reconfigure our applications?
Usually not: virtual servers move as they are. Any IP address, licence or external connection changes are listed during inventory and go into the plan.
Can physical servers be migrated too?
Yes. Physical servers are converted to virtual servers first, then moved with the same plan and rehearsal steps.
How do we know the monthly cost after the move?
Sizing is based on measured usage, so the items that drive the monthly cost are visible before the move. Usage is tracked in the first months and oversized servers are scaled down.
How is the migration priced?
Migration is priced as a project by the number and complexity of systems; the price is given in writing once the inventory is done.

About the related products

Private Cloud

How are my resources separated from other customers?
Your resource quotas, network and users are reserved for your organisation. Your organisation's network traffic passes through its own gateway.
How does it differ from Virtual Servers?
A private cloud gives your organisation a resource pool with CPU, memory and storage limits, its own gateway and its own user management. With Virtual Servers you take servers one at a time; with Private Cloud you create the servers inside the pool yourself.

Virtual Servers

How are virtual servers priced?
Each server is billed on the number of vCPUs, the amount of memory and the disk size you choose.

Business Continuity

What workloads can I protect with Business Continuity?
Workloads running in virtual machines in your on-site environment. Which servers are protected is chosen server by server in the quote.
