Data That Will Be Migrated

All settings in IMSS or IMSVA will be migrated to Trend Micro Email Security completely or partially except those listed in Data That Will Not Be Migrated. Among the settings that are partially migrated, some are modified to adapt to Trend Micro Email Security due to the feature differences between IMSS or IMSVA and Trend Micro Email Security. Therefore, you need to confirm or fix these settings according to the on-screen instructions after migration.

The following table lists some examples of the settings that will be partially migrated and describes the feature differences.

Note:

For details about all the settings that are completely or partially migrated, see the data migration report downloaded from the Trend Micro Email Security administrator console when the migration completes.
