Permission Levels (Best Practices)

Follow this chart to see the required or recommended permissions for certain actions:

Permission Levels
Site Collection Administrator	Recommended for all procedures in Management and Migration. Needed for OneDrive for Business operations in Migration for each MySite at both the source and destination environments.
Farm Administrator	Needed to copy site collections from a web application when running a Copy Structure in Migration.
Global Administrator	Needed when you have to list all your Site Collections and for Office 365 Groups manipulations (migration of permissions, and listing in the ShareGate Desktop Explorer)
Site Owned Permissions	Needed to copy from a SharePoint 2003 source when running a Copy Structure in Migration.
Term Store Administrator	Needed to copy managed metadata for all actions in Migration.
Full Control	Recommended when running a Copy Content, Import from File Share, and Import from Google Drive in Migration.
Manage User Alerts	Needed to copy user alerts in Migration (note that you also need to have the server extension installed at the source and destination).
Read-Only Lock	Should be removed on your source Site Collection before running a migration action with ShareGate Desktop. Some SharePoint services do not respond correctly when the Site Collection is on read-only mode (even if they are only used to read information), and the requests will not be processed as intended.
