Data migration has started in batches. A mapping issue with santech addresses was found in the first batches which caused a failure for 5 migrated users. The mapping has been fixed for these users and that are being rescheduled after their batches are completed.
At the current time there are 11 users completed and 16 are migrating. We are seeing that migration times vary widely based on number of messages and the size of the mailbox. This will push the migration toward smaller batches of users at a time. The smaller batches will allow the batches to run quicker and let me fix and remigrate any failed users.
