Promotion of First Level Subsites to Site Collections
|
Navigation: How Content Matrix Handles Various SharePoint Components > Promotion of First Level Subsites to Site Collections |
If you are migrating to SharePoint Online using the Paste as Site Collection option (or the PowerShell Copy-MLSharePointSiteCollection command) you have the option to promote first level subsites to site collections on the Site Collection Options tab. You can also configure promoted site collections as hub sites.
NOTES:
·If a corresponding site collection does not exist on the target, a new site collection will be created. If a corresponding site collection already exists, the existing site collection will be updated.
·If the source subsite has its own subsites, those subsites will be migrated as subsites of the promoted site collections on the target.
Prerequisites
The option to promote subsites is enabled only:
·if you are migrating from SharePoint on premises to SharePoint Online using a Microsoft 365 tenant connection on the target
·the source site contains at least one subsite
·the Copy Child Sites recursively option is selected
·the target template is Team site (no Microsoft 365 group) (STS#3) or Communication site (SITEPAGEPUBLISHING#0)
Mapping of Source and Target Templates
When a subsite is promoted, it is migrated to the appropriate modern template on the target.
|
Source Template |
Mapped Target Template |
|---|---|
|
Publishing/ Wiki |
Communication (SITEPAGEPUBLISHING#0) |
|
All other templates |
Team site (no Microsoft 365 group) (STS#3) |
Limitations
Some objects in migrated subsites, such as Lookup columns referring to the parent site and workflow/workflow associations from parent site, may not be migrated properly for the promoted site collection.

If you are migrating to SharePoint Online using the Paste as Site Collection option and have chosen to promote first level subsites to site collections, you also have to option to either:
·associate the promoted site collections on the target to an existing hub site
OR
·register a new hub site for the promoted site collections.
MySite Migration

Navigation: How Content Matrix Handles Various SharePoint Components > MySite Migration |
The following are the supported source/target combinations for migrating MySites:
·Any source server with SharePoint 2007 or later (using the Web App or Farm connection types) to any supported target server (using the Web App or Farm connection types).
·Any source server with SharePoint 2007 or later (using the Web App or Farm connection types) to an Microsoft 365 Tenant environment.

When migrating MySites, the target side connection must be a Web App or Farm connection type, using the Local Object Model or Metalogix Extensions Web Service (MEWS) connections for on premises installations of SharePoint. For Microsoft 365 target environments, the Microsoft 365 Tenant connection type must be used. This allows users to connect at a Site Collection level to the Microsoft 365 environment so they can run Site Collection migrations. It is recommended that the Web App or Farm connection types be used on the source side as well. Other connection types can be used on the source, such as the Database connection. However, this will have some limitations. If these other connection types are used on the source, MySites can still be migrated to the target, but they will be migrated as Site Collections (not using the MySite template), and as a result, will not include some of the User Profile data and other data that the normal MySite migration will preserve. When migrating SharePoint MySites, a Local OM or a Remote OM connection can be used. However, due to some User authentication changes that have been made beginning in SharePoint 2013 that inadvertently restrict the creation of Site Collections (MySites are a type of Site Collection), using the SharePoint OM remotely, Content Matrix needs to use a set of elevated permissions to create Site Collections. In order for these elevated permissions to be used, the migrating user account must explicitly (by name) have "Full Control" permissions on the Web Application that the Site Collection is being created on. A preliminary check will be made before elevation occurs to ensure the migrating user has enough permissions initially to be able to use the elevated Site Collection creation. Creating Site Collections with the Local OM connection type does not have this same restriction, but the same permissions are recommended in case elevated permissions are needed. Please see Connecting to SharePoint Online for more details on this connection types. For more information on this specific issue, please see SharePoint Site Collection Creation Issue. Note that in order to view MySites when migrating to an Microsoft 365 Tenant environment, the Include Microsoft 365 tenant my site host connection check box must be enabled when the connection is created. The MySites are then displayed under their own top-level root node. For more information, please see Connecting to SharePoint Online. |

Migrating MySites to a Target that Uses OneDrive
|
Navigation: How Content Matrix Handles Various SharePoint Components > MySite Migration > Migrating MySites to a Target that Uses OneDrive |
When migrating MySites to a target SharePoint environment that uses OneDrive, Content Matrix will use a slightly different method to migrate some of the content. Any documents on the source that are in the MySite Shared Documents or Personal Documents library will be migrated into a Shared with Everyone folder in OneDrive. This is done instead of migrating the documents into Document Libraries of the same name. As a result, this can cause some navigation copy issues because the Shared and Personal document libraries will not exist on the target, and because they do not exist, they cannot be added to the navigation.
Additionally, web parts that exist on landing pages in SharePoint 2007 or 2010 will not be migrated.

IMPORTANT: If you are migrating to OneDrive on a SharePoint Online target, Owners, Members, and Visitors groups must be created on the target. If these groups are missing, an error will occur. See Error: 'The object is associated with property AssociatedMemberGroup.' in the Frequently Asked Questions section.
