what happens if I import registry keys from a selected branch of registry folders and keys from Win 2003 Server to Win 2008 Server

I was told that I should be able to import the HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI contents to the same folder which is empty on my clients machine. How dangerous is this to export from my Windows 2003 Server to my clients 2008 server? My personal machine has all the drivers.  ( I am responsible for the outcome I am aware ) If I export that "selected branch" , when I go to import it does it know to place it in the same location on the new machine? Like this:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI

In other words I do not have to do anything different to import it other than just point to the exported file click import and it will do the rest? Do you know if I need to restart or anything like that or put any files in the appropriate location. I was also told about the odbccad.exe file being put in the C:\Windows\sysWow\  folder?

Can anyone verify this? See images below.
