• Your destination organization have all repository names identical to repositories in source organization
• You have ownership/admin permissions in the destination GitHub GHES/GHEC where you want to migrate to
• You have ownership/admin permission in the source GitHub GHEC/EMU where you can migrate from
• You need to create a GitHub Personal Access Token with all repo permission admin:org permission in your source URL and authenticate for the source organization if the org is behind SAML/SSO
• You need to create a GitHub Personal Access Token with all repo permission admin:org permission in your destination URL and authenticate for the destionation organization if the org is behind SAML/SSO

You need to either export these environment variables.
