Office 365 to Office 365 Migration Guide - While Changing the Domain Name

    This is a great guide, my concern is that it is labeled as "Office 365 to Office 365 Migration Guide" yet it only covers the email part of Office 365. When during this process do you start the OneDrive to OneDrive migration? I already know there is an article for OneDrive to OneDrive Migration Guide - but it still does not help me to understand if OneDrive migrations only start after the Full Mailbox Delta-pass or do you complete mailbox pre-stage > OneDrive pre-stage > mailbox delta > OneDrive delta > DMA....?

    Hi Gary Cook,

    The Document Migration Best Practices article provides some information about the best migration strategy for your scenario. We recommend OneDrive for Business to OneDrive for Business migrations to be performed using a single pass or a quick-switch migration strategy. I've re-written the migration strategy section of the OneDrive for Business to OneDrive for Business Migration Guide, so please check it out again and let me know if you have further questions.

    Hi Rob, if I don't want to migrate the data. I only want to move the source email addresses as additional smtp address in target tenant. Is there a tool that I can run against source tenant to check for any dependency in deleting domain. Thanks

    I have a few questions regarding #7 - the cutover. After removing the domain from the old MS O365 tenant to add to the new tenant, what happens to the email addresses? Do we need to reconfigure MigrationWiz? I would appreciate some more clarification on that process.


    Thank you,

    Under "MSPComplete Steps", when I Create the Customer I must specify Primary Domain.  Do I use old (existing) domain or new domain?
