2TB 3 partition bootable MBR to 3 partition bootable GPT 4TB drive

You could.
1. initialize the target 4tb disk to gpt and create esp and msr partitions on it.
2. mount your acronis image as a physical disk
3. use something like winntsetup wincopy to migrate from the mounted image to the gpt disk.
I haven't tried using diskgenius os migration to migrate from mounted mbr image to gpt disk, that might also be a way to do it. **************************************************************************************************** ******** A different way is to restore the mbr image to the the 4 tb disk. Then convert the 4tb to gpt afterwards and adjust the partition sizes. Unless you know what you are doing, you might end up with the esp partition in an awkward place.

That seems to make the most sense if I can figure out the details.
A friend of mine wants to use Macrum Reflect. I'm not familiar with it so I ran a trial copy. It looks like all it is is another image/file copy which I can't see working. No provision to change any type of formats or anything else, just backups or similar. I explained the situation, but he must of missed alot of the details. Anyone know anything about this from the UK?

He only referred to this one program to do all of that which didn't make sense to me unlike what you posted earlier (which is over my head).

I will know when I get the drive, probably in a few days. I will see what he has to say. I'm not impressed with that Macrium Reflect so far, it's images are 1/3 larger then what True Image produces. That AOMEI Partition Assistant has it over MR for the preparation functions.
One step at a time.

Update;

Long story short, with the help of a tech friend he finally got the drive switched over to GPT with a added, hidden partition and boot as a UEFI drive ok.
BUT,
Only by itself, when I connect the MBR SSD drive and try to boot from the GPT drive it errors our with a supposed hardware like error. That is selecting the UEFI drive as the boot drive in the BIOS boot menu. The MBR SSD 'Main system drive still boots fine. The MB is a Gigabyte GA-970A-D3P v2.

Any ideas?

The 2nd route, except only one additional hidden partition was created, not counting the 2 data partitions duplicating the 2TD drive. The work was done remotely thru 'TeamViewer' which he has done from many years and a land line.
He used AOMEI Partition Assistant DiskPart and Macrium Reflect. He created the 'Hidden Partition' with DiskPart IIRC.

Here is the screen shot of the 3 drives, #2 is the new 4TB and the created partition.

Don't take this the wrong way, yes, but I'd rather have him do it. If I do it and it's wrong for whatever reason I'll get the blame.
IOW's I don't want to 'break it any more.
I would like to see the procedure with the file package if that is ok with you..
