Question 1

Can email migration take place without interrupting work?

Accepted Answer

The migration plan is designed to minimise operational impact, but we do not make a blanket no-downtime promise. Before work begins, we assess domains, mailbox count, data volume, devices and dependencies, then schedule potentially disruptive actions at an agreed time.

Question 2

Is Microsoft 365 a backup?

Accepted Answer

No. Built-in retention and recovery features do not automatically replace an independent backup strategy. Backup scope, retention period and restoration responsibility are selected separately.

Question 3

Who owns the tenant and domain?

Accepted Answer

As a rule, the tenant, domains, billing accounts and data should remain under the customer’s control. Sigma Vision receives only the agreed, named and limited access necessary to perform the work.

Question 4

Can existing Microsoft 365 licences be used?

Accepted Answer

We first review their edition, assignment, terms and the team’s actual needs. The possibility of using, changing or purchasing licences is confirmed individually before a proposal is issued.
