The source system "WIN2K8R2" in this migration scenario is running Windows® 2008 R2 and is configured as a file server and domain controller of the domain "DomainA.Com".
The target "SYNOLOGY" is a Synology® NAS configured as domain controller of the domain "MyDomain.Com". It has the Active Directory and the DNS packages installed and configured. You can find a video explaining how to setup AD & DNS on a Synology® in this video.
There are local and global domain groups and users in the source Active Directory. Users are members of global groups, the global groups are members of domain local groups and the domain local groups are used in share level and NTFS permissions (AGDLP principle).
There are two file shares, "Sales$" and "Support$" that will get migrated to the NAS system, including all users, groups, file shares, share permissions, files, folders and NTFS permissions.
The migration is performed in two steps in this example, first the user and group accounts using a "User and Group Migration" type of job and then the data using a "Data Migration" job.
