Clone to a different size SSD.

Thread needs solution

...and I just hit a mouse button and erased my question!!!!!!

I want to clone a two partition 500GB SSD to a new three partition 1TB SSD.  Is there a standard way to do this?

My best idea is: clone two to two, making the new one small for the OS and BIG for the data.  Then partition the BIG one into two afterwards. Even if I loose data, I can recopy it over without affecting the OS.

Thx, Jon

Jon, welcome to these public User Forums.

Sorry but you are misunderstanding what cloning is about here!

See the link in my signature to the document describing the difference between cloning and using Backup & Recovery.

A clone is a 1:1 duplication of the source disk to the target disk.  Any data or partitions on the target disk will be wiped out immediately when the operation is started.

Please see KB 56634: Acronis True Image: how to clone a disk - and review the step by step guide given there.

Note: the first section of the above KB document directs laptop users to KB 2931: How to clone a laptop hard drive - and has the following paragraph:

It is recommended to put the new drive in the laptop first, and connect the old drive via USB. Otherwise you will may not be able to boot from the new cloned drive, as Acronis True Image will apply a bootability fix to the new disk and adjust the boot settings of the target drive to boot from USB. If the new disk is inside the laptop, the boot settings will be automatically adjusted to boot from internal disk. As such, hard disk bays cannot be used for target disks. For example, if you have a target hard disk (i.e. the new disk to which you clone, and from which you intend to boot the machine) in a bay, and not physically inside the laptop, the target hard disk will be unbootable after the cloning.

It is strongly recommended to make a full disk backup of the source drive before embarking on an clone operation.  This is your safety net in case of any issues arising that could leave you with an unbootable system!  You should also create the Acronis rescue media too!

See KB 63226: Acronis True Image 2020: how to create bootable media and KB 59877: Acronis True Image: how to distinguish between UEFI and Legacy BIOS boot modes of Acronis Bootable Media

...well... actually I've already cloned 3 laptops successfully.  Each had it's own little quirks.  I always did it with the original still in the laptop, and the SSD connected by USB.  The first, I learned about UEFI, the second actually booted the first time I swapped them, and the third was an older laptop and I had first changed the SSD to GPT when I should have left it MBR.  Live and learn.  They're all 3 working perfectly.  In each case I also adjusted the partition sizes before cloning.  No problem, so yes, I know what cloning is.  That still leaves the question 'what if I want to go to 3 partitions from 2'?  It will be SSD to SSD and GPT to GPT.  I'm sure I can get it by trial and error, but if you have a suggestion, I may save some time.  
Thx, Jon
