Pre-Check Parameters in Migration App

Any user of the Migration App.


When a new migration job is created, Migration App automatically runs a pre-check scan to provide insights to the Migration Operator about how the job will run.

What is analyzed during pre-check?

Migration App analyzes the following items during the pre-check scan:

  1. What is the total size of the migration job?
    By default, most domains are limited to a maximum size of 5TB for an individual migration job, but we recommend creating jobs totaling less than 4TB to allow for data creep. If your job is over 5TB, you cannot run the migration, although this limit can be adjusted by exception. Reach out to your Egnyte representative to discuss.
  2. How many files and folders?
    The number of files and folders combined equals the total objects in the job. By default, total objects are limited to 8 million., which means jobs with more than this limit cannot be run. However, this can sometimes be adjusted by exception. Discuss your options with your Egnyte representative.
  3. Are there empty folders on the source?
    You will have the option to include empty folders in your migration, should you so desire.
  4. Will any files and folders be excluded?
    Excluded objects are those that cannot be migrated to Egnyte for a variety of reasons. See
    Unsupported Characters and File Types.
  5. Are any files and folders unsupported?
    Unsupported files and folders are those with names that do not comply with Egnyte’s naming protocol. As opposed to excluded objects which cannot be migrated at all, unsupported files and folders may be migrated to Egnyte if you first Sanitize them. See
    Understanding Sanitization Options in Migration App
  6. How much space is available on the domain?
    This helps to inform you if the migration job will exceed your current plan limit.
  7. Will the migration job exceed the available space on the domain?
    For standard trial domains, your job will fail if you try to migrate more than 20GB. For paid domains, this is just for your information. You can migrate as much as you want, and if the storage exceeds your current plan it will be addressed during the next billing period.
  8. Are there any individual files on the source that exceed the limit for the Egnyte domain?
    Every domain has a limit to the size of any individual file. This is dependent on your plan and could vary anywhere from 100GB to 250GB. If any individual file exceeds the limit for your domain, it will simply be skipped during the migration.
  9. Are there any folders on the source that exceed the 50,000 child limit?
    Egnyte has a hard limit of 50,000 immediate children within a given folder.  If any folder in your migration project exceeds this limit, it will simply be skipped during the migration.

How do I view the results of the pre-check scan?

Results will be displayed on the Migration Details page in the Scan information drawer.
