-Before using [the old method of user contribution mapping](#old-method-of-user-contribution-mapping) for imports to GitLab Self-Managed and GitLab
-Dedicated, you must meet certain requirements. Imports to GitLab.com use an [improved method](../../import/mapping.md)
-that doesn't require preparation.
-
-These requirements are:
-
-- Each GitHub author and assignee in the repository must have a
-  [public-facing email address](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-email-preferences/setting-your-commit-email-address).
-- The GitHub user's email address must match their GitLab email address.
-- If a user's email address in GitHub is set as their secondary email address in GitLab, they must confirm it.
-
-GitHub Enterprise does not require a public email address, so you might have to add it to existing accounts.

 ## Known issues
 
 - GitHub pull request comments (known as diff notes in GitLab) created before 2017 are imported in separate threads.

 The GitHub importer uses an [improved method](../../import/mapping.md)
 of mapping user contributions for GitLab.com, GitLab Self-Managed, and GitLab Dedicated.
 
-### Old method of user contribution mapping
-
-You can use the old user contribution mapping method for imports to GitLab Self-Managed and GitLab Dedicated instances.
-To use this method, `github_user_mapping` must be disabled.
-For imports to GitLab.com, you must
-use the [improved method](../../import/mapping.md) instead.
-
-Using the old method, when [user accounts are provisioned correctly](#accounts-for-user-contribution-mapping), users are mapped during the import.
-
-If the requirements are not met, the importer can't map the particular user's contributions. In that case:
-
-- The project creator is set as the author and assignee of issues and merge requests. The project creator is usually the
-  user that initiated the import process. For some contributions that have a description or note such as pull requests,
-  issue, notes, the importer amends the text with details of who originally created the contribution.
-- Reviewers and approvals added on pull requests in GitHub cannot be imported. In this case, the importer creates comments
-  describing that non-existent users were added as reviewers and approvers. However, the actual reviewer status and
-  approval are not applied to the merge request in GitLab.
