Prerequisites for Data Migration

Before migrating data from IMSS 9.1 or IMSVA 9.1, make sure the following has been done:

Add, provision, and verify the domains you want to manage through Trend Micro Email Security.

For details, see Adding a Domain.
Synchronize with LDAP servers using the Directory Synchronization Tool if IMSS or IMSVA has enabled LDAP settings.

The Directory Synchronization Tool is available under Administration > Directory Management.

For details, refer to Directory Synchronization Tool User's Guide.
Enable IMSS or IMSVA to support Trend Micro Email Security migration by doing the following:
1. On the IMSS or IMSVA management console, go to Administration > Updates > System & Applications and check the build number.
  
  If the build number does not meet the following requirements, install the latest service pack and hotfix.
  - IMSS 9.1.0.1357 or later
  - IMSVA 9.1.0.2011 or later
2. Enable the hidden key in the IMSS or IMSVA admin database by running the following SQL statements:
  
  Note:
  IMSS and IMSVA use the same configuration file imss.ini.
  
  insert into tb_global_setting (section, name, value, inifile)
  
  values ('imp_exp', 'enable_ems_migrate', '1', 'imss.ini');
Export configuration files from the IMSS or IMSVA management console under Administration > Import/Export.
