How to migrate a non-DFS file servers? We will talk about the high level migration steps to migrate Windows File Server Role to a new Windows Server in the same domain.
First of all, make sure both file servers were joined to a same domain. Then, administrators can check which folders are sharing by using "Computer Management" or performing "net share" on "Command Prompt".
Remark: ADMIN$, IPC$, C$ are default share of file servers.
After that, administrators can perform "Robocopy" to copy the folder with NTFS permissions from old server to new server or use backup software to back up and restore the folder and file with the same NTFS permissions to a new server.
