With the help of the Archive360 technical staff we were able to install the FastCollect software very quickly and after migrating several mailboxes we had enough knowledge to begin exporting of all mailboxes to Office 365. First, we ran batch jobs, based on functional units, migrating the active mailbox to Office 365 using PowerShell and the tools providing by Office 365, and cutting over to the online mailbox. Next, we migrated the email archive data to the Office 365 archive mailbox using the FastCollect application. These jobs would run for several days with no impact to the customer. Our assigned support professional from Archive360 would log in remotely periodically and check the logs and adjust server and application settings to fine tune the migration performance. Any time I had questions or concerns, support was just a quick email or phone call away. I always dealt with the same person that was assigned to this migration. The software provided excellent logging so it is easy to zero in on any issues and re-run jobs if need be. At the end of the project, an excellent report detailing any exceptions provided assurance that we had captured the data as well as possible.
