Introduction:
Om Enterprise Inc., a US-based managed IT services provider, needed to migrate 312 Exchange mailboxes containing approximately 1.5 TB of mailbox data from one on-premises Microsoft Exchange Server to another Exchange Server hosted in a different Active Directory domain.
The migration involved servers located in different cities and connected over the internet, creating additional challenges around network latency, bandwidth limitations, data integrity, and business continuity. With a large volume of mailbox data to transfer, Om Enterprise Inc. needed a reliable migration solution that could simplify the process while minimising disruption to users.
To address these requirements, the organization selected Stellar Migrator for Exchange. The solution enabled the IT team to carry out the cross-domain Exchange migration efficiently while limiting downtime to approximately one hour.
Background:
Founded in 2002, Om Enterprise Inc. is a US-based MSP Partner with Stellar. They offer managed IT services, cybersecurity, server infrastructure, VoIP solutions, remote IT support, and data backup and disaster recovery services for small and medium-sized businesses.
As part of its infrastructure requirements, Om Enterprise Inc. needed to move from one on-premises Exchange Server to another Exchange Server located in a different Active Directory domain.
The project involved migrating 312 Exchange mailboxes containing approximately 1.5 TB of mailbox data. Since the source and destination servers were located in different cities and connected over the internet, the IT team needed to manage network performance while ensuring mailbox data was migrated successfully and business communication remained available with minimal interruption.
“ Statement from the customer:
Stellar Migrator for Exchange was easy to install and use. With excellent support from the Stellar team, we successfully migrated 312 mailboxes (1.5 TB) with only about one hour of downtime. We highly recommend it for its ease of use and reliable support
”As a managed IT services provider, Om Enterprise Inc. needed to ensure that the migration did not significantly disrupt business communication or day-to-day operations.
Before beginning the migration, the key priorities were:
- Successfully migrate all 312 Exchange mailboxes without data loss.
- Preserve mailbox data throughout the migration.
- Minimize downtime for end users.
- Complete the migration across different Active Directory domains.
- Manage network latency and bandwidth limitations during the internet-based transfer.
- Maintain business continuity throughout the migration.
With approximately 1.5 TB of mailbox data involved, even network-related performance issues could have increased the migration time and affected users. The organization therefore required a migration solution that could support a large-scale Exchange migration while keeping operational disruption to a minimum.
Attempted Solutions:
The migration required the IT team to address several technical and operational challenges associated with the existing Exchange environments.
The key challenges included:
- Migrating mailboxes between different Active Directory domains.
