File Server Migration between two domains without trust

Hello,
I have two domains and I need to migrate the file server from one domain to another on a different machine however I have to do this operation without using trust relationship.

I need a software which will list groups and users from both domains and prompt me for group and user mapping and do the migration with security.

It's perfectly fine to make the mapping manually. I just need a file server migration software that can migrate between domains.

When talking about file server migration they are always talking about file servers within the same domain. I have new groups and users on the new domain because I cannot use AD migration tool. There is no trust and cannot be made for management reasons.

Microsoft FSMT is no good since unknown SID handling is not what I need.

Thank you.

Look into subinacl with the option /offlinesam, the object_type /subdirectories and the action /changedomain=OldDomainName=NewDomainName[=MappingFile[=Both]]
You might want to use robocopy to copy the (empty, "/create") file structure including permissions to a USB disk or whatever, attach it to a machine in the new domain, and try the SID replacement with the copy.

Do NOT use the subinacl found in the ResKit, it's buggy; install this after the ResKit:
SubInACL (SubInACL.exe)

As I said before FSMT is not the answer. I will be migrating from one domain to another. Unresolved SID handling is too bad for FSMT. It does not let you make a mapping instead it gives everyone, or whatever permission you want to all unresolved SIDs.

In my scenario all of the SIDs are going to be unresolved. I will give subinacl a try.
