2  Before you start

Before you start migrating, consider the following:

Duration of the migration process

Before starting a migration, bear in mind that time consumed by the migration process depends on size on accounts involved. It is recommended to get the network and all users involved ready for outage of email services and for migration in low-load time. Migration can be also done step by step by smaller groups of users.

CSV file with user accounts

Migration requires preparation of a CSV file that would include users and their passwords. This information is crucial for access to the source IMAP server. Make the data in the csv file follow this pattern: user@domain.com;password;Full Name.

Public and archive folders

Public and archive folders cannot be migrated by the standard procedure. If you, in spite of this fact, need to migrate also these folders, move them to the mailbox of any user included in the migration first. The folders will then be migrated as private folders.
