Swap 3TB Fusion drive for a 6TB
When I bought my iMac I ordered it with the optional 3TB fusion drive. There is a recall on this drive and is going to be replaced for free under Apple's recall campaign for these failing drives. I have AppleCare so a tech is coming to my house to swap the drive out. (The same thing happened 3 years ago with my 21.5" iMac. When the tech came to my house I paid him to install a new 3TB drive instead of the replacement drive Apple provided to him.)
I have almost maxed out the 3TB Fusion drive and figured as long as the drive was getting replaced anyway, I might as well replace it with a 6TB drive. The physical action of replacing the drive should be the same regardless of capacity (the new drive's physical dimensions and operating specifications are exactly the same, just the brand and capacity are different.)
So my question is this: Is the software setup going to be an issue? I know that Apple's firmware automatically configures the Fusion setup if I were to reformat my existing drive. But will it do it automatically with a brand new drive of a different capacity? Will I just be able to have the tech install the drive then boot up in Recovery Mode, run Disk Utility to partition and format the drive, then install OS X without having to do anything special prior to or after I swap the drives?
Thanks to anyone who can provide some insight to this.
Is this a good question?
