Is there any way we can do the copy function during business hours or is it recommended to do this after business hours.

Hello,

We are currently having 4 exchange servers with about 6000 mailboxes.

OS : Windows 2008 R2 SP1

Exchange 2010 SP3 RU13 

Dell Migration Manager 8.12 is used to copy mailboxes to Office 365 Tenant.

When the copy job is attempted , users cannot work in their outlook sessions. Outlook sessions freezes .

Is there any way we can do the copy function during business hours or is it recomended to do this after business hours.

 

Checked the below article :

https://documents.software.dell.com/preparing-migration/8.12/release-notes/known-issues?ParentProduct=1042

Users will not be able to use Microsoft Outlook to log on to their mailboxes while the Mail Source Agent is processing them within a Remote Users Collection. If a user is working online, Microsoft Outlook will not operate while the mailbox is being processed. After mailbox processing has been completed, a user must log off and log back on to the mailbox

Please advise on the issue.

    Good Day,
    If you upgrade to the newest version of Migration Manager (8.13) you can use MAGE (the newer agent) to process the mailboxes, not in a Remote User Collection with Exchange 2010 as the source. This will allow access for your users to continue working.

    With your current version, "Remote User collections" aren't always the best way to go, I would suggest you just setup regular mail sync if you are experiencing the current issue per that KB.

    You have some options, but sounds like RUC (remote User Collection) wouldn't be the best way to go, unless you absolutely have to preserve the users OST.

    Hello Luke,

    Thank you for the reply. I am pleasantly surprised for the fast answer.

    Is there any hotfix applicable for migration manager 8.12 which can resolve the outlook freezing issue. Users are using outlook 2010 in online mode and not cached exchange mode.

    If upgrading to 8.13 will resolve the issue , then we will perform this.

    No, there is no update to 8.12 that will help this situation, it's the way the RUC works. If you upgrade to 8.13, you can use MAGE to synchronize the mailboxes, and the users can remain online.

    If you want users to still access their mailbox during the migration you will need to change the way in which you migrate the mailboxes.

    Because you're migrating to Office 365 you will need to use the Unified Mailbox Synchronization agent which does not copy the mailbox but synchronizes the mailbox.

    Here is the documentation on setting up a collection to Office 365.
