I then run a second time with a --delete switch to catch anything that changed while the first run was going (A full sync of my mail store can take well over 24 hours!). The second run will go much faster, depending on the size of the initial run. Finally, I will mount RO, so I know nothing is changing and run a final sync, which usually only takes a couple of minutes, then light up the new system. If you already have a system dump/restore you could also just use rsync as the final step to catch the stragglers. -Markham
