If the OS version is the same, there should be absolutely no need to relink. In your case, though, you are changing the kernel version, and probably the glibc version as well, so a relink should be in order. (This would not be the case if Oracle binaries were linked statically, but being linked dynamically, bad things will happen when the system libraries change.)

You'll find it convenient, I think, if you mount all of the filesystems in the same locations on the new server, and you'll probably find it even more convenient if you keep all the (numeric) userids and groupids the same across servers.

Have a look at the procedures for "cloning" an Oracle_Home. There is a little work you will need (want) to do in order to properly set up the Oracle Inventory on the new server. If you don't, you won't be able to apply patches. On Linux, this amounts to creating a directory or two, and a small handful of symbolic links, as I recall. You can probably work out and execute the needed steps yourself in 30 minutes, but there are easier ways.
