Cloud

A hosted environment for a quick start. Together, we look at region, performance and the scope of the contract.

IceWarp as a hosted environment. We look at the available EU hosting options, user licenses, storage and the right migration path.

On premises

Run it on your own infrastructure, with agreed requirements for maintenance, backups and security.

Installation on your infrastructure with DNS, certificates and backups. We tailor architecture and operation to your requirements.

Hybrid with Microsoft 365

A shared domain and a gradual switch for parts of your team. We plan and test coexistence and routing before the changeover.

A switch with a clear plan.

We clarify the number of users, existing systems, data volumes and requirements. Then we agree the approach, time windows, testing and support.

Migration

We take stock of existing mailboxes, calendars and workflows and prepare the switch step by step.

Plan. Migrate. Support.

  1. Planning

    Record the number of users, existing data, DNS and the services you need.

  2. Set-up

  3. Migration

    Transfer mail and calendars, using IMAP, PST and coexistence as appropriate.

  4. Operation
