Setting Migration Defaults

To simplify the site migration, you can set a default site owner that will be used if the actual owner (user account) is not found in the target. See the details on user mapping below.

Caution: If both the actual owner account and the default owner are not found in the target, the migration task will fail.

  1. Go to the migration project Dashboard in case you use new migration UI.
  2. Click SharePoint widget.
  1. Click Configure Project on the project dashboard.
  2. In the Edit Project dialog, provide the user from the target tenant and click Save.

You can set a different default owner for a group of sites by overriding this setting in the migration task.

User Mapping Workflow

During the migration, On Demand Migration gets the accounts associated with the migrated (source) site and then looks up their pairs in the target tenant. Depending on the results, one of the following actions is performed:

  • If a matched target user is found, On Demand Migration sets it as an owner of the migrated site.
  • If a matched user is not found on target, On Demand Migration switches the site owner to the default account.
  • If the actual owner account has no match on the target and the default owner is missing, the migration task fails.

This table describes how ownership is handled by On Demand Migration depending on the SharePoint entity:

SharePoint Entity Matched owner found Matched owner missing Matched owner and default user missing
Top-level sites (site colections) Target account matched with source owner Default target user Migration Task fails
Subsites System account

System account

Lists

Folders Target account matched with source owner Default target user
Files Target account matched with source owner Default target user
List Items Target account matched with source owner Default target user

Setting Custom SharePoint Admin Center URLs

On Demand Migration builds the expected SharePoint Admin Center URL based on SharePoint's default naming convention. If a customer has custom SharePoint Admin Center URLs, these URLs should be set manually as described below:

  1. Click Configure Project on the SharePoint migration dashboard.
  2. In the Edit Project dialog, change default source and/or target SharePoint Admin Center URLs to the custom ones and click Save.

IMPORTANT: On Demand Migration does not validate SharePoint Admin Center URLs. These URLs are a subject of special request to Microsoft. Do not change the default URL if the custom one is not yet approved by Microsoft.

Migrating sites

Use the SharePoint contents tab to migrate SharePoint objects (sites, lists, web, members). You can migrate an entire site or initiate granular or incremental migration. You can navigate through SharePoint site objects and identify any site objects that failed to migrate.

Populate SharePoint sites

TIP: Before you begin, ensure the account migration has finished (or at least that all SharePoint users are migrated).

To populate On Demand with SharePoint sites

The simplest approach is to populate On Demand with all supported site collections. Alternatively, see the next set of instructions to populate On Demand with a defined list of site collections.

From the SharePoint contents tab

  1. Click DISCOVER SITE COLLECTIONS.
  2. From the New Discovery Task dialog, Discovery Options tab, make sure Discover all supported site collections is selected.
  3. Complete the New Discovery Task dialog.
    • Schedule when the task will be started. See Task Scheduling for details. Click Next to view the task summary.
    • Check scheduled start of the task and name the task. Give informative names for the tasks. It will greatly simplify the project management and event filtering in the future.
    • Click Finish to save or start the task depending on schedule option selected.
  4. SharePoint sites will be added to the table in On Demand. On Demand will set the object state of each site to discovered. Learn more about Object and content states.

To populate On Demand with a defined list of SharePoint sites

Step 1: Prepare the list of SharePoint sites:

  • The list of SharePoint sites will all be in one column of a CSV formatted file.
  • On Demand will read data from column name URL or Source URL.
    • On Demand will read the column name from the first line of the CSV file.
    • If the CSV file contains both URL and Source URL column names then the first encountered column will be read.
    • If the CSV file contains other columns they will be ignored.
    • The CSV file can contain one column.
  • On Demand will read the URL of each SharePoint site from the URL/ Source URL column, one URL per line.

Step 2: From the SharePoint contents tab

  1. Click DISCOVER SITE COLLECTIONS.
  2. From the New Discovery Task dialog, Discovery Options tab, select Discover selected site collections from file.
  3. Click Browse to locate the CSV file.
  4. SharePoint sites from the CSV file will be added to the table in On Demand. On Demand tests the site URL is valid before adding it to the table, ensuring that it exists and that is is based on the support site template. On Demand will set the object state of each site to discovered. Learn more about Object and content states.

To populate On Demand with SharePoint site contents

You can populate the site structure and content without triggering a migration. This is how you do it.

In populating the site structure and content you will better understand the scope of the migration. The SharePoint contents tab will be populated with the following SharePoint object types: Site (site collection), Web (root site), Lists, Webs (sub sites, child sites). The display will include such information as the number of lists and the number of items in each list.

From the SharePoint contents tab

  1. Locate the site.
  2. Check the site. You can check multiple sites to populate the contents of multiple sites.
  3. Click DISCOVER SHAREPOINT CONTENTS.
