I am slowly migrating the data etc off an old CentOS32 4.x server to a
new CentOS64 5.x server.  The old server only has 15Gbyte of its hard
drive in use.  Is there an easy/safe way to copy the entire contents
of old server root directory to a directory on the new server for
future reference?  Most of the data is various test files, perl
scripts, etc. scattered all over.
