Миграция на 38 пощенски акаунта от Microsoft Exchange 2013 към Microsoft 365 – завършена за 4 дни
The ITeOn team successfully migrated 38 email accounts from on-premises Microsoft Exchange Server 2013 to the Microsoft 365 cloud platform (Exchange Online). The project covered:
- Planning and analysis of the current infrastructure, including assessment of the Exchange server, mailbox sizes and network environment;
- Transfer of over 938 GB of data distributed among all users, without loss of information and with full preservation of the structure, metadata and shared resources;
- Configuration of Microsoft 365 accounts, including licensing, access policies, security and MFA (multi-factor authentication);
- Phased migration with zero downtime – users continued to work without interruption during the entire process;
- Post-migration support, including updating Outlook profiles, configuring mobile devices and assisting with adaptation to the new platform.
The project was implemented within 4 working days, with minimal workload for the client’s team and full accountability during all phases. With this project, we demonstrated not only technical expertise, but also a strategic approach to the modernization of the IT environment with a focus on security, reliability and sustainability.
