Migrate OS+files with TM or Migration Assistant?

[komatsu]

Normal working OS X.

I need to import files, apps and settings onto a new HDD.

Is it best to do a

a) Time Machine backup first

OR

b) attach drive to USB and use Migration Assistant?

I recommend:
a) Time Machine backup first
AND
b) attach drive to USB and use Migration Assistant

I always believe in having alternatives (Plan B). Using Migration Assistant with you old drive should work fine if there are no problem with it.

I recommend having a Time Machine backup just in case. BTW, you should be able to use Migration Assistant on the Time Machine backup.

ok thanks for that.

Should there be any difference between route (a) and route (b) in terms of success, speed, data integrity, whatever ?
