Refer to this document - MigrationWiz Environment Preparation Guide - for information on what is required during this phase. The source and destination environments are setup the same way as a standard MigrationWiz project. The emails will need to be decrypted before they can be migrated. Encrypted Emails: For all Source email systems, any email sent or received using encryption methods will not migrate using MigrationWiz.There are exceptions to this rule, but they are not consistent. These events will need to be recreated at the destination. Calendar meeting links: Lync, Skype or Teams events will be migrated but will usually not work in the destination because the links are for the source environment.Pictures that have been added within a Business Card, under Contacts.Personal Messaging Resource Management (MRM) Tags.Mailbox rules and folder permission settings (these are only supported from Exchange Server 2010 SP1+ and later to Exchange Server 2010 SP1+ and later).Mailbox sharing settings (aliases delegates client settings).Server-based and dynamic distribution lists.Personal distribution lists ("Contact groups" in Microsoft 365).Acceptance status for meeting participants.User-defined/custom fields for Contact items.Modified description text & modified attendee lists for exceptions to recurring meetings.Calendar permissions (Exception for Exchange sources outlined below).Custom items that do not inherit from the core system types.Important: If an item type is migrated into a folder of a different type at the destination, the item will not be visible. Items that do not match folder types, i.e.These items and settings will NOT migrate: Once the migration is complete, you could set sharing/permissions on the calendar so that it can be accessed by other users.


For those cases, when the user's mailbox is migrated, we should be able to migrate the resource mailbox calendar as one of the user's calendars. In some cases, the resource mailbox is just a shared calendar that is owned by a user. If there is no way to log in to the resource mailbox using a web client (like OWA), then we also cannot log in and migrate the data. If you can log in to the resource mailbox using a web client (i.e., Outlook Web Access), we should be able to log in as well, and migrate the data. We handle resource mailboxes the same way that we handle regular user mailboxes. Basic Authentication must be enabled in the Office 365 tenants.The maximum individual file size that MigrationWiz can support is 60GB.We are not able to support migrations with two-factor or multifactor authentication.Only a single-target domain is supported.Due to the types of calls made to the destination during coexistence migrations, IP Lockdown cannot be used with autodiscover.However, you can still migrate to or from GoDaddy using this guide instead: Exchange Online (Microsoft 365) to Exchange Online (Microsoft 365) Mailbox Migration Guide Due to limitations on connections put in place by GoDaddy, we do not support migrating to or from GoDaddy using this specific migration type.We do not have “live” monitoring of changes (as with a sync agent) and we cannot handle scenarios such as conflict resolution without user interaction. If changes are made at the source after migration, they will not sync to the destination, nor will changes made at the destination sync to the source. MigrationWiz is a migration tool, not a syncing tool.Please refer to the setup guides pertaining to Azure AD scenarios to see how best to setup and configure your migration. To learn more about any of the processes outlined in this article, visit the Microsoft 365 Mailbox Migration FAQ.Īzure Active Directory Connect (ADFS, AADConnect, and synchronization systems) are now a supported option in our Coexistence product. We strongly suggest that you review the Exchange Online (Microsoft 365) to Exchange Online (Microsoft 365) Mailbox Migration Guide before starting this migration. There are several prerequisites and best practices for this type of migration. If you have never performed a migration before, we suggest reading that before beginning the steps outlined in this scenario. If this is your first time performing a migration, we have created a Migration Planning & Strategy Guide to walk you through planning, set-up, and general migration best practices.

This is also known as a 'Slow Burn' migration effort.Īpp password usage is not supported by this endpoint.

A coexistence strategy is used when a migration is planned to take many weeks or months with users being migrated in batches, and the users will need to continue to seamlessly contact each other. This is the complete onboarding task flow for migrating mailboxes from one Microsoft 365 tenant to another Microsoft 365 tenant while using coexistence.
