My name is Juul with GIS Support group. To address your question, moving an FGDB to an SDE instance is not as clear as a step-by-step workflow. This is mainly due to permissions, versioning schemes, and other schema options that might come into play during a migration. As such, this kind of workflow is usually handled by our services team and not by our support group. Technical Support can help if the services team run into an issue during the process, but we don't oversee nor facility the process in its entirety.
As such, I advice you to contact your account manager Thiago Carvalho to process such a request to our services team.
