Important information

The Kerio migrator archive is saved, extracted and ran on the new IceWarp server or any other server. IceWarp Kerio Migrator Tool functions as a portable (Windows) executable file. Execute KerioMigrator.exe in the administrator mode (Run as administrator) to run the migrator.

CAUTION: After the Kerio migrator is ran for the first time, the configuration file kerio-journal.mig is created. This file stores the entire configuration and access data. Do not delete the kerio-journal.mig file. The deletion results in a new, blank migration process, and the migrator overwrites everything in the target destination.
