We recently replaced our aged Xserve G5 with a Mac Mini server running 10.8.2 and have it configured and up and running smoothly for our small workgroup.
Shortly thereafter the new NEW Mac Mini was released which is faster and has higher capacity drives -- so we purchased one.
I need to make the new (late 2012) Mac Mini identical in setup to the slightly older Mac Mini excepting of course for the disc sizes. The new one has two 1TB drives as opposed to two 750GB drives.
My question is this: Cloning the data drive is a no-brainer and that will be complete in about 30 minutes from now. But I'm trying to decide whether to clone the OS drive from the (slightly) older machine to the new one. That would be the easiest path, but I know the new Mini has some slightly different hardware, such as USB 3.0 ports -- so I am concerned the clone may not be perfectly bootable or would somehow not be fully compatable with the new machine. But...maybe it would be fine.
Here's what I've decided to do and I'd love some feedback and advice on the plan from the smart people in this room:
On the NEW machine I will partition its existing 1TB OS drive into 3 partitions.
Partition 1: Will have the original, untouched OS that it came with (ie: this will be the original single partition simply re-sized downward and NOT erased).
Partition 2: Will be amply large enough for me to clone the older machine's OS drive to, and I will use Carbon Copy Cloner to do so.
Partition 3: I will leave blank for future use as a data partition or whatever I'd like.
Seems that this way I can try the cloning approach and if it works, great! If not, then I still have the originally installed OS on the new machine and can pursue using Migration Assistant to see how well that works. It should work fine since I'm going from 10.8.x to 10.8.x -- but I do hear horror stories about trying to use Migration Assistant.
Is the above a sound approach?
