For Customers with 1000 users or more
The product group has also requested the following information in the request.
example to extrapolate appropriate values for your request.
If you want to migrate 100 users simultaneously, the service request may include the following information:
PowerShellMaxTenantRunspaces 400 :
In one minute, per tenant, the runspace creation/delete count should not exceed 400
PowerShellMaxRunspaces 40: In one minute, per user, the runspace creation/delete count should not exceed 40
PowerShellMaxConcurrency 20 : One user can create 20 concurrent remote PS at most
PowerShellMaxTenantConcurrency 200: Tenant can create 200 concurrent remote PS at most
PowerShellMaxCmdlets 1000: The max cmdlet execution number in 1000 seconds
NOTE: These recommendations are subject to change. We are working directly with Microsoft to identify appropriate values to include in the requests and will update this article as additional information becomes available.
This value should be set to evenly distribute the max tenant runspaces granted by Microsoft across the migration machines that will be used. If the machines are sharing an MNE SQL database, the max tenant runspace number granted by Microsoft should be divided by the number of migration machines to arrive at the value for this setting (i.e. set MaxPowershellConnections=limit/#servers). If the migration machines have separate MNE SQL databases, you will need to set the value through a machine connected to each database, but the total should not exceed the max number allowed so round down with this calculation.
MNE’s Admin Pooling feature should be utilized to automatically create admin accounts for each thread. For example, if you are planning to run 10 machines with 10 threads each, Admin Pooling should be enabled and set to 100 admin accounts. NOTE: When using MNE, you will need to turn off Admin Pooling if attempting to reset Office 365 passwords and license mailboxes in Office
For Customers under 1000 users
To determine the appropriate value for this setting, take the default tenant max runspace limit of 9 and divide by the number of migration machines you plan to use. For example, if you wanted to use 3 migration machines for your migration, you should set MaxPoweshellConnections=3. You should round down when calculating this value so, if you want to use 4 migration machines, set MaxPoweshellConnections=2
NOTE: When using MNE, you will need to turn off Admin Pooling if attempting to reset Office 365 passwords and license mailboxes in Office 365 during the same program run.
