Not so much, these days, if you are sensible.

This is fair. As a side note, under /etc/udev you will find the
configuration file that binds the persistent names (eth0, etc) to your
hardware, which you may need to alter if you want to change those
persistent names.

Actually, these days you would have to be kind of silly to use something
other than mount-by-LABEL or mount-by-UUID[1], given the fairly dynamic
nature of device discovery.
In that case you system will just work(tm) on the new hardware, because
it identifies what to mount based on the filesystem, not the hardware it
happens to be sitting on top of.

Footnotes:
[1] I prefer the later, because the chance of a conflict is zero, while
the former is pretty high — especially with some distributions
naming their root partition '/' uniformly.
