Migrating Mailboxes from Exchange and Kopano to grommunio

The migration of mailboxes between different email systems can be a complex task. grommunio has now developed a PowerShell script that facilitates the move of Exchange mailboxes. This script exports each mailbox as a PST file and allows for import on a Linux server. This significantly simplifies and accelerates the migration process.

For users of Kopano, the former Zarafa, a suitable tool is also available. The migration of Kopano mailboxes occurs similarly to that of Exchange, making the transition easier for companies that use both systems. The provision of these tools demonstrates grommunio's commitment to making the switch to their platform as smooth as possible.

Challenges in Migration

Despite the provided scripts, there are challenges that must be considered when migrating mailboxes. Particularly shared mailboxes represent a greater effort, as they are often used by multiple users simultaneously. Managing these mailboxes requires careful planning and coordination to ensure that all users can seamlessly access their data.

Another aspect that must be considered during migration is the clients accessing the mailboxes. Compatibility of the clients with the new system must be ensured to facilitate a smooth transition. This may require additional testing and adjustments to ensure that all functions work as intended.

Support for users during the migration process is also of great importance. Training and assistance are necessary to help employees adapt to the new environment. This can increase the workload for the IT department, as they must ensure that all users receive the necessary information and support.

Experiences from CANCOM

CANCOM has already conducted an extensive project for the migration of mailboxes, during which 21,660 mailboxes were moved from Exchange to grommunio. The experiences from this project show that careful planning and execution are crucial for the success of the migration. The IT department of CANCOM worked closely with grommunio to identify and apply best practices.

User feedback after the migration was predominantly positive. Many appreciated the improved user interface and the new features that grommunio offers. The IT department was able to make the migration process more efficient by utilizing the provided scripts and minimize downtime for users.

The migration of mailboxes to grommunio presents an attractive option for companies, especially those already working with Exchange or Kopano. The provided tools and scripts enable a structured and manageable migration that meets the demands of the modern working world.
