If you're using 'cp', add the '-a' option to keep
permissions, timestamps, and such unchanged.
If you do it right and are reasonbly lucky, the operation
_should_ be successful. I'd recommend making backups before
starting, just in case.
Other ways to do the transfer would be 'tar' or 'rsync'.
With 'tar', you can verify the tarball against the original
and then verify destination against the tarball. With
'rsync', you can do an incremental update just before making
the switch to avoid losing log entries and such. I'd
recommend rebooting to make the change effective.
You might consider using Knoppix to do the copying and to
make the changes to /etc/fstab. That way, you're not trying
to change a running system, so it can't get the rug pulled
out from under it.
(Yes, that is one of my email addresses.)
