New-MoveRequest in batch

dss ds 526 Reputation points

We are migrating a large number of mailboxes. 127 of them

27 of them are over 7 Gig in size, ranging from 7Gig to 36 Gig

EAC > Migration is slow so I think PowerShell: New-MoveRequest would be the way to go.

However, it does;'t move SystemMailboxes.... I can do this with EAC, but doesn't move via cmdlet

since there is a large batch, we are using this:

Get-Mailbox -Database MB1 | New-MoveRequest -TargetDatabase MB2 -BatchName "MB1toMB2"

All seems ok, so do we have to do system ones separately ? For no other reason, than just making uninstalling old exchange eaiser.

I'll take suggestions if there are better/quicker ways to accomplish this.

    Hi @dss ds ,
    There are two ways to migrate mailboxes, using EAC or using PowerShell. Using PowerShell would be a better option because EAC can have a variety of errors.
    After my search, there is an article that may be helpful in migrating your mailboxes:
    Microsoft provides third-party contact information to help you find additional information about this topic. This contact information may change without notice. Microsoft does not guarantee the accuracy of third-party contact information.
    Batch operations that you mentioned are also achievable, which would be a relatively better approach. New-moverequest documentation is also available for you if you need to refer to it:

    I do recommend moving mailboxes with the New-MoveRequest as it’s faster, and there is no Migration mailbox involved in the process. If you need a detailed report after the mailboxes finish moving, go for New-MigrationBatch.
