Email System Migration Plan

Minimize risk with an email system migration plan

While migrating email to Microsoft® Office 365™ is not without risk, the right email system migration plan can help to mitigate problems and streamline the process.

Your email system migration plan must address several areas of risk. Whenever email stores are moved from one system to another data loss and corruption is a real threat. Security is another issue, as certain protections may be unavailable for a period of time during migration, exposing data and users to a variety of email-borne threats. Since migration to Microsoft 365 email hosting often requires email systems to go offline temporarily, minimizing downtime and loss of productivity is critical.
