Kerio Exchange Migration Tool (KEMT) is a free tool for migrating public folders, accounts, and user data (Email, Contacts, Calendars, Tasks, Notes) from your Microsoft Exchange Server to Kerio Connect:
Preparing for the migration
See the Kerio Connect product pages for supported versions of the Exchange server and Microsoft Outlook.
The duration of the migration depends on many factors, and may take some time. If possible, perform the migration during light usage hours.
The Exchange migration tool does not overwrite or remove the existing data in the destination Kerio Connect mailbox. Therefore, you can run the migration tool on active Kerio Connect mailboxes, and the data will be merged.
Direct users and new email to the destination Kerio Connect server, so that users do not change data on the source Exchange server either during, or after the migration process.
Before you start
Migrating the data
Users should create new accounts/profiles in users' email clients to avoid data inconsistence.
Interrupting the migration
If you interrupt the migration process, KEMT saves only the completely migrated data of the user currently being migrated.
Before you start the migration process again, delete the partially migrated user in Kerio Connect. Otherwise the data will be duplicated after you migrate the user again.
See the migration Report log for details.
Migration process logs
Kerio Exchange Migration Tool generates various logs addressing the migration process. They are stored in the KEMT installation folder in \logs\MMDDYYYY_HHMMSS.
Each start of the migration tool generates a new log.
After completion of each migration, read through this file to make sure that no errors occurred and that all user accounts have been migrated correctly.
If users had not been mapped to Kerio Connect before the migration, the Report log includes new user passwords generated by the migration tool.
Information in this log is useful especially for the developers. If you have any issues during the migration process, this log can help the Kerio technical support find the solution.
