Microsoft Exchange Online in Microsoft Office 365: Migration Case Study

*860K mailboxes moved from on prem to o365.
*interesting strategy: user's online accounts were created, dial tone mailboxes were created, user data was imported in separately. this strategy allowed the migration to happen very fast. the school/districts involved had tools to migrate exchange data to online solution - 180 schools/entities were uploading data concurrently. early on during the pilot test, full armor (vendor) noticed that the data export was failing - b/c so much data was coming into online service, the hosted system saw this as DOA and closed down the connection. the lesson learned here is to work with the migration specialist from MS prior to migrating your data

*full armor wrote up a tool that aids in migration, Quest now owns it and it's downloadable
