Advanced Options for Microsoft 365 - Source

While the default options are recommended for the majority of organisations, CloudM Migrate gives users the ability to customise their migration experience. The following are some of the Advanced Options available to customers migrating from Microsoft 365. Changing some of these options will change the way data is migrated.

SharePoint Online

SharePoint Migration API - SharePoint Migration API is recommended for all migrations to SharePoint Online and OneDrive for Business. For more information see the article here.

Retry Count - The number of times an operation will be attempted before failing.

Document Sharing/Permissions - Choose whether the document should be shared as per the source file ACLs if they can be resolved to email addresses (see documentation).

Default Document Library Name - When migrating Microsoft Teams/Microsoft Groups/OneDrive this document library will be mapped to the default document library in the destination.

Hybrid Environment - Allows a custom 'SharePoint Admin Url' and 'SharePoint My Sites Url' to be entered for hybrid migration.


Excluded Item Classes - Specify the list of item classes that will not be processed as part of a migration. Exact matches are made on the value specified here.

Included Item Classes - Specify the list of item classes that will be processed as part of a migration. Wildcard matches can be used.

Migrate SMIME Signed Messages Without Modification - When migrating SMIME signed messages, perform no modification of the messages. This could mean some other features of CloudM Migrate may not be executed, such as moving attachments to Drive or ensuring the sent address is correct. It will ensure however that the digital signature verifies.

Primary Contact Type - Choose either SMTP or SIP address when resolving contact email addresses.

Exclude Group GAL Contact Aliases - Exclude additional email addresses (aliases) when resolving a Group GAL contact.


Migrate Non-Organizer Attendee Statuses - Attempt to migrate attendee statuses for appointments where the migrating user is not the owner (when the owner is being migrated attendee statuses are always preserved). Due to API limitations, for any appointments from outside of the domain and from any accounts that no longer exist the attendee status will always not be migrated.
