It is important to entrust migration to qualified, experienced professionals, who are able to qualitatively assess the IT structure of the organization and choose the best scenario for moving to the cloud.

First of all, the organization must define its long-term goals. Typically, they are as follows:

  • Hybrid deployment – If a company needs to store part of mailboxes and documents on a local server, while others are to be in the cloud. In this case, a hybrid deployment will be required: some of the mailboxes remain on the server, while the others will be migrated to the cloud.
  • Full cloud migration – If an organization plans to completely transfer the entire email data structure to the cloud, then a full migration will be required. In this case, it is important to correctly assess the current IT infrastructure of the company, the specifics of business processes, conduct the necessary expertise. Choose the means and methods of migration based on the identified data.

  • Current IT infrastructure type: where will mail be transferred from?
  • The number of boxes to move to the cloud.
  • Which migration option do you choose: full or hybrid.

What Email Service Are You Migrating From?

If this is the case, all mailboxes, folders, distribution groups, existing sorting rules, contacts, calendars, and tasks are to be transferred to the cloud. It is best when all the information is migrated to the cloud in one go.

The process usually takes several days. This option is ideal for small and medium-sized organizations that value the simplicity and convenience of the script.

Are You Planning a Migration and Want to Support Some Mailboxes in the Current Mail System?

In case you want to migrate over 1,000 mailboxes, need a staged migration or pilot deployment, then a phased migration option will suit you. This scenario will allow users or groups of mailboxes to be moved to the cloud over time, while the rest will remain on the on-premises mail system.
