Migration from One O365 tenant to another O365 without third party RRS feed

  • Question

  • Dear Team,

    We have customer who is looking for large migration from one O365 tenant to another , we are talking about migrating about 10k users , we don't want to use a third party tool,

    We know about a TechNet article that say you can do it manually ,

    https://support.office.com/en-gb/article/How-to-migrate-mailboxes-from-one-Office-365-tenant-to-another-65af7d77-3e79-44d4-9173-04fd991358b7?ui=en-US&rs=en-GB&ad=GB

    But we would like to do it manually using scripts , need some ideas to that out of the box, which also efficient and fast,

    Also as we understand any third party would pick the data from one tenant and put to another,

    Looking forward,

    Hasan Reza,

  • Appreciate your response Philip,

    I am in dire need of help , I have huge tenant to tenant migration, and every one just keeps on asking me to do it using third party ,

     

    Frankly, coming from scripting and programming background , I have managed to do some real complex migration like Domino to Exchange 2013/Office365, Rackspace to Office365 , Gmail to Office 365 ,

     

    All using the native MS native tools and PowerShell,

     

    I just don’t want to do this via any third party , main workloads to be migrated are mailboxes only, and in some cases one drive , no other workloads need to migrate

    , I need something out of box , after all any third party app would also be using some kind of multi threaded copy process , forming multiple end points then coping data for each mailbox using these end points,

    Please advise, I am sure this will benefit many others like me,

  • Hello,

    Office 365 doesn’t support PST exports using PowerShell, but you can use eDiscovery to export users’ mailboxes to PST files: http://www.codetwo.com/admins-blog/how-to-export-office-365-mailboxes-to-pst-using-ediscovery/?sts=6474.

    And then bulk-import them to Office 365 using any of these options: https://support.office.com/en-us/article/Overview-of-importing-PST-files-and-SharePoint-data-to-Office-365-ba688e0a-0fcb-4bd7-8e57-2b669564ea84.

    "I need something out of box , after all any third party app would also be using some kind of multi threaded copy process, forming multiple end points then coping data for each mailbox using these end points"

    Correct. For instance, our solution – CodeTwo Backup for Office 365 - uses EWS API: https://msdn.microsoft.com/en-us/library/office/dd877012(v=exchg.150).aspx#bk_EWSMA.

    The issue is, that MS doesn’t offer endpoints for direct tenant-to-tenant migrations. So what most solutions will do, is download data from the source tenant, temporarily store it somewhere, and then feed it to the target.

    Of course, you could do the same thing on your own. This would mean writing your own application that does what I described.

    Opting for a 3rd party solution seems more resource-effective here. The advantage of CodeTwo Backup for Office 365 is that you can first use it to migrate data and then as a backup utility.

    If you would like to test the program, here you can download a free trial version: http://www.codetwo.com/backup-for-office-365/download?sts=6474.

    Hope this helps,
    Adam (CodeTwo)

  • Dear Adam,

    I am really thankful to you for the guidance, I am almost there where I have been able to create connect two tenants simultaneously a common endpoint, rest is figuring the download and upload process,

    As far as the Solution you have provided I shall also double check that,

    As for now it is fingers crossed,

    Bye,

    Hasan Reza,

  • If you need a migration solution to migrate all your data (mailboxes, SharePoint sites, Google Sites, Google Drive, OneDrive) between Google and Office 365, here is a SAAS solution: Cloudiway. 

    It moves the users, groups, contacts, assigns the licenses automatically and migrates the emails, SharePoint sites and OneDrives.

    It's worth trying the FREE TRIAL as it will save you time and money.
