This works but has a some disadvantages. First, it is very slow. Then you |
| 8 |
copy all filesystems as-is, including any fragmentation (which may be |
| 9 |
significant if the old disk is nearly full). Also, rearranging the |
| 10 |
partitions can be extremely time consuming, and not that straightforward |
| 11 |
if you are moving partition start points. |

A different sized disk generally deserves a different partition layout, so |
| 14 |
starting from scratch and copying only the data is a better option. |

You can also substantially reduce downtime by first rsyncing while the |
| 17 |
system is running (using either -x or bind mounts). That will give a |
| 18 |
slightly inconsistent root, so you then repeat the process from a live CD |
| 19 |
(using --delete with rsync) to clean things up. The latter rsync takes a |
| 20 |
fraction of the time as 99.*% of the data is already cpied. |
