Migrating from previous versions
When migrating from a previous version’s message archive to version 6.2 and later:
- Before doing the migration, all messages in the database cache must be archived into the external database.
- Use the version 6.2 and later database. The previous version’s database cannot be used as the database version has changed.
- Configure message archiving for each thread. The internal alert takes effect according to the configuration.
Remove the previous version’s external alerts. Although the previous version’s external alerts can work in version 6.2 and later, it is best to remove them. Version 6.0 and later uses internal alerts.
