Step 2: Scan and assess Dropbox folders

  • Article

After you connect to Dropbox, add the source paths to scan and assess your Dropbox folders.

After you connect, scan and assess your Box user accounts.

  1. Select Add folders from the menu bar to choose how to add folders:
    - All new folders to autodiscover all new users in Box
    - Single folder for only one account, or
    - Multiple specific folders to bulk upload folders by entering them into a CSV file to upload.
  2. Choose to Automatically start scanning now or choose to scan later.
  3. Select Add.
  4. Highlight any or all of the accounts and then select Scan if you chose not to auto scan earlier.

Important

The total number cannot exceed 50,000 tasks.

  1. Once the scan is complete, a table summary displays to give you an at-a-glance overview of your folders. The summary includes Folder item counts, migration readiness, and any issues that need attention.
  2. Review the scanned folders. Search for specific text, or select a filter to review the list more easily.

Download reports

Summary and detailed scan reports are available to assist you in troubleshooting. Download the generated reports and logs to investigate any possible issues that might block your migration.

  1. Once the scan is complete, select Download summary report.

  2. To download a detailed scan report for an individual account, select a single row, then select Download scan log.

Managing users who own large amounts of data

Upon completing your scan, download the scan reports and review/address any large source data owners.

The more users simultaneously being transferred, the higher our throughput for your migration. Users with large data sets should be broken into smaller Service Accounts to facilitate faster transfers.

Important

To maximize throughput, users should not own greater than 100,000 items or 1 TB of data. The more users you have, and the smaller the amounts of data they own, the faster your migration proceeds.

Examples:

Size Action
If a user owns more than 400,000 items Divide the items between four users each with 100,000 items.
If a user owns more than 5 TB of data Divide between five users so that each user owns 1 TB.

To create Service Accounts, you can work with your Dropbox Admin to carry out the following steps:

  1. Once you have identified a large user, determine how many Service Accounts will be required (see example above).
  2. Create the Service Accounts in Dropbox and assign them a license.
  3. From the original large user, identify the folder(s) you would like to assign to the Service Account.
  4. Change the ownership of said folder(s) to the new Service Account. This may require that the original owner first share it with the new owner, where the new owner would have to accept, then the original owner will then have the option to select them as owner. The original owner becomes co-owner of the folder and the permissions reflect that new status in the Source account. The folder will no longer appear in their My Files folder but will now appear in Shared with me.
  5. When it comes to migrating the Service Account, create a corresponding OneDrive user/SharePoint site to migrate the new Service Account content to.
  6. Before making any changes, you should reach out to your tenant administrator, investigate any source custom solutions or integrations that you might be using, and determine if these ownership changes have any impact.

When mapping please ensure that each Service Account has its own unique matching Destination account to optimize performance.

Source Path Destination Path
originaluser@contoso.com originaluser@contoso.com/[upload folder]*
serviceaccount1@contoso.com serviceaccount1@contoso.com/[upload folder]*
serviceaccount2@contoso.com serviceaccount2@contoso.com/[upload folder]*
serviceaccount3@contoso.com serviceaccount3@contoso.com/[upload folder]*
