Resolution:

1. Use AppManage -batchExport to export all the applications from the old domain.
2. Use exportDomainSecurity to export security(users and roles) configuration in the old domain
3. Create a new EMS based domain which requires a database to store domain and application data.
4. Then use AppManage -batchDeploy/-batchUpload to import all applications to the new domain.
5. Use importDomainSecurity to import configuration to the new domain.

For more information on AppManage, please refer to TRA script deployment documention.
For how to use exportDomainSecurity/importDomainSecurity, please refer to Administrator documentation.
