Copy/Migrate FileVault 2 encrypted hard drive
SSD is different, it needs a separate driver from OS to work properly. It is better that you archive your drive using time machine, install OS X as usual and than, during the last install step, restore your home directory. This will ensure that your system uses all correct drivers and your SSD will live a healthier life.

When archiving with time machine, you can drag /System into the exclusion list to avoid archiving OS X itself (you'll be reinstalling it).
