windows2003 to windows2012

Have windows2003 server with few folder shares and its permissions.
I am using robocopy to mirror the files, I now have to create shares on the windows2012 server.
What is the best way to do that?
In windows2003 i used to import the reg key , but they were both same os level. not sure I can do that between windows2003 to windows2012.

If the server is on the same domain it can be fairly easy - assuming you're on the same domain.

export the following registry key from the 2003 server - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Shares

Then make sure the drive letter and paths is the same - for example, if you had on the 2003 server D:\Users shared, make sure the new server has the same drive letter and path - D:\Users.

Then you can just double click on the .reg file you exported from the 2003 server on the 2012 server.
