swapping functions of drives via dupe; then renaming
 

In addition to a few other drives, all with SuperDuper bootable clones of my system drive on them, I have the following three SSDs:

SSD A (my current, functioning system drive, internal to my iMac)
SSD B (an empty, unused SSD, also internal to my iMac)
SSD C (an external SSD with a SuperDuper bootable clone of A. It is connected via Thunderbolt 1 cable to my iMac.)

Each is on its own physically separate SSD. None is a partition sharing the same SSD with anything else.

I want for A and B to stay where they are inside my iMac but for them to trade functions: I want for B to function as my system drive and for A to become empty and available for another use. (Why? Because A is too small in GB capacity to accommodate my system-drive needs; B is twice the size.) I want for C to remain unchanged.

My questions are:

Should I simply use SuperDuper (while running it on A) to clone A to B? Or should I use SuperDuper (while running it on C) to clone A to B? Or should I use SuperDuper (while running it on A) to clone C to B? Or should I use the Disk Utility “Restore” tab, in some way?

Also, how can I best accomplish these drive-naming goals?:

Currently,
A is named “Boot”
B is named “Temp”

Eventually, I would like for B to be named “Boot” and for A to be named “Temp”. I would like for the volumes and the drives themselves to be named this way—not just the volumes.

Many thanks,

Mark

Hey, Mark, I already responded to your email about this. I'm not sure why you posted in two places...?

Hi Dave.

Sorry about that: I posted in the Discussions forum before knowing that you had already replied to my email message. After sending my email message to you but before knowing that you had replied to me already, it occurred to me that maybe my question was more appropriate for the Discussions forum than for an email to you (I thought maybe you would prefer to answer it in the forum, or to give others the opportunity to reply, too). I'm sorry for any inconvenience I have caused; I really appreciate your having helped me with this matter.

Humbly,

Mark
