Data Migration takes place in two ways:
Dynamic Migration takes place when an existing Messenger Express user logs into Communication Express. The users receive an email after the migration is completed.
In the dynamic migration process:
The application checks if migration has been enabled in the uwcuath.properties file and then proceeds with the migration process.
The login logic then compares the nswmextendedprefs attribute with mepabmigration value to determine whether the user’s data has been previously migrated.
Once PAB migration is completed, the Addressbook Server sets the nswmextendedprefs, mepabmigration to 1 in the logged in user entry, to indicate the completion of the migration process.
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 define the parameters mentioned in Post Configuration Steps.
In the batch migration process, migration takes place at the server level without end user interaction. The administrator executes the runMigrate.sh batch script to migrate the mail users PAB data present in a given domain. For mail users present in multiple domains, the administrator will have to invoke the runMigrate.sh script for each domain to migrate users PAB data from the given inetDomainBaseDN to the Address Book Server.
