We use this program to migrate inboxes from Cyrus to Google Mail.

Scalable architecture. Celery queue driven interface for managing tasks. You can match the number of workers to the queue size and reduce turnaround time.

Django Webapp. Easily modified Django frontend allows users to prepare themselves and begin migration on their own terms.

Presynchronization. Nightly bulk pre-sync for faster migrations.

Task generation script. Python script to generate bulk task sets for presync or final sync.

LDAP integration. Queries LDAP for inboxes to sync.
