NOT TRUE. Paragon is a piece of junk. I purchased the 4.0 version & tried to move my 8.1 OS to a SSD. The SSD would not bootup & there is no tech support available within 24 hours. ... I SPENT SEVERAL HOURS TRYING TO GET THIS TO WORK BUT PARAGON FAILED EVERY TIME!!!
My good fortune was to contact Paragon Tech Support the day of purchase and who spent time solving my problem. To my mind it was a weird problem which I would never have solved on my own. Here is what they said "Hello Stephen, Thank you for your reply. According to logs you have boot files on D partition (130GB) and OS installed on C partition (178GB). Most likely program tries to migrate full D partition (130) with boot files plus full C and your target disk don’t have so much space to storage.
It should be fixed with next: 1) Download and install Backup and Recovery 14 Free with the link below.

2) Prepare recovery media with recovery media builder (installed with B&R14Free) as described in the next article to make it safe.

3) Open command prompt and type next line: bcdboot C:\Windows /s C:
4) Run B&R14Free and use right click on D partition – set as inactive. Use right-click on C partition – set active. Apply changes. Then please reboot computer to check if it’s bootable. If you are succeed then the problem should disappear. Try to migrate once more."
