Sun Java System Communications Express 6.3 Administration Guide

Dynamic Migration

Dynamic Migration takes place when an existing Messenger Express user logs in to Communications Express. The Users receive an email after the migration is completed.

    In the dynamic migration process:

  1. The application checks if migration has been enabled in the file by checking the pab_mig_required parameter.

    If the pab_mig_required parameter is set to true, the migration process is initiated.

  2. The login logic then compares the nswmextendedprefs attribute in the user's LDAP entry. It checks for the value of the mepabmigration parameter to determine whether the user’s data has been previously migrated.

  3. Once PAB migration is completed, the Address Book Server sets the nswmextendedprefs, mepabmigration properties to 1 in the logged in user entry, to indicate the completion of the migration process.

  4. The user receives a mail after the PAB data is successfully migrated to the Address Book Server.

To receive a mail, you are required to set the parameters in the file.

Tip –

It is recommended that the administrator sends an email to all users informing them that PAB data migration will be triggered during the first login and as a consequence they will not see the Address Book data during the initial sessions. Users should contact the administrator if they are unable to see their data after 2 or 3 days.
