Overview
DryvIQ supports connections to Microsoft OneDrive for Business Government Community Cloud (GCC) High--an environment that provides compliance with US government requirements for cloud services platforms. Connections can be made using an administrator account with the proper privileges to manage configurations. DryvIQ creates this connection using the OAuth 2.0 flow to simplify login and connection management.
Do not select the “Microsoft Office 365 GccH (OAuth 2.0 Deprecated)” connector. This is the old connector that uses CSOM, which Microsoft is deprecating. Select the “Microsoft Office 365 GccH” connector when creating the connection since it uses Microsoft Graph API, which results in better job performance.
Creating a Connection
Expand the Manage section in the left navigation menu.
Click Connections.
Click Add connection.
Select Microsoft OneDrive for Business GccH as the platform on the Add connection modal.
Enter the connection information. Reference the table below for details about each field.
Click Sign in with Microsoft OneDrive for Business GccH.
Enter the email for the account being used to create the connection and click Next. You must use an admin account with the proper privileges to manage Microsoft 365 configurations.
Enter the password for the account and click Sign in.
You will see a green "Connected” message on the bottom of the modal when DryvIQ establishes connection. (If the connection fails, verify the information you entered.)
Click Done to finish creating the connection.
Add Connection Modal for Microsoft OneDrive for Business GccH
Field | Description | Required |
|---|---|---|
Display as | Enter the display name for the connection. If you will be creating multiple connections, ensure the name readily identifies the connection. The name displays in the application, and you can use it to search for the connection and filter lists. If you do not add a display name, the connection will automatically be named. | Optional |
URL | Enter the URL of your Microsoft OneDrive for Business GCCH High account. You can find the URL by logging into Microsoft OneDrive for Business GCCH High using the account you want to use to create the connection. The URL in the address bar is the URL you need to use. | Required |
Token endpoint | This setting is rare for most Microsoft connections and can be left blank. If needed, this value will be provided by your administrator. | Optional |
Graph API endpoint | This setting is rare for most Microsoft connections and can be left blank. If needed, this value will be provided by your administrator. | Optional |
External users notifications | This indicates if you want to send notifications to external users. The default value is No, so no notifications will be sent. If you select Yes, notifications will be sent to external users when they have been granted access to content based on permissions. | Optional |
Behavior When Deleting Items | Select the type of delete DryvIQ should perform when deleting items: Permanent or Soft. Soft delete is the default delete behavior; however, Permanent is the recommended behavior. A soft delete marks items as a deleted. You can still access them to restore or permanently delete the items. A permanent delete removes the items. This delete is not reversible. | Optional |

Connection Pooling
Microsoft Office 365 connections using OAuth 2 authentication may experience bandwidth throttling from Microsoft when using connection pooling.
HTML Files
SharePoint online does not support uploading HTML files larger than 256 MB. If your migration includes HTML files that exceed this limit, the file transfer will fail, and an entry will be logged in the audit with the following message: "Unable to interpret the contents of this page because it exceeds the maximum page size of 268435456 bytes.”
Impersonation with Batch Mode
When using Impersonation with Batch Mode, SharePoint Online shows “System Account” in the activity rather than the impersonated user. This is expected behavior for batch mode/bulk migration API. With batch mode off, the impersonated user will display in the activity panel.
Invalid Characters and Spaces
DryvIQ verifies file and folder names to identify unsupported characters based on the platform. It then replaces invalid characters with an underscore (_) so the files and folders can be transferred.
The logic includes leading and trailing spaces in file and folder names. DryvIQ replaces the space rather than trimming it because trimming the space could cause duplicate file names. Adding the underscore ensures the name remains unique.
DryvIQ will sanitize file names that contain combined Unicode characters by replacing the characters with an underscore (_).
Mapping
When creating CSV mapping files for import, the usernames must be lowercase to properly adhere to the search requirements for the connector.
Metadata Mapping
If a library requires specific metadata but the metadata is missing from a file being copied into the library, the file will be flagged and will not transfer on subsequent jobs runs. If you have files stuck in a flagged state due to missing metadata, you may need to manually transfer the files and add the required metadata.
Timestamps
There is a discrepancy in timestamps for the SharePoint Online Folder Created Date when using CSOM and Batch Mode. This behavior is a known issue within OneDrive for Business/Office 365.
DryvIQ will attempt to preserve timestamps on folders when using both CSOM and the batch API. However, SharePoint Online updates the folder's modified dates whenever a file is uploaded into it. As a result, when using CSOM, the timestamps will be preserved when the folder is initially created but then updated after every file that gets uploaded. When using batch API, it preserves the timestamps on the folders after all of the files within the batch are committed. This is the cause for the discrepancy between the two methods.
Version Deletes
Version deletes are supported.
Corrupt Files
If you see “Error=Value=CobaltAllZerosDetected” errors in the logs, the file that triggered the error will not be uploaded to SharePoint online. Microsoft produces this error for files it considers to be corrupt.
