transfer data to a new SATA drive

[claytowne]

I purchased a new SATA drive to replace my current primary drive and already have a second drive in place. How do I transfer the data from the primary drive to the new drive. I thought about powering down, taking out the second drive and put in the new one and try to transfer that way, then upgrade to the new OS. Is ok or is there a better way?

'... thought about powering down, taking out the second drive and put in the new one and try to transfer that way [using 'SuperDuper' or 'CarbonCopyCloner'], then upgrade to the new OS.' - nice plan.
