Paragon Migrate OS To SSD V.4 System Migration Software Review And Tutorial


When we first launch the “Migrate OS to SSD” software, we receive a welcome screen.


Note the last sentence / disclaimer, referring to the inability to migrate “dynamic volumes.”  Examples of this would be RAID or caching setups.  Click “Next” to continue.


If your destination SSD were to become unplugged prior to a migration attempt, you would receive the above screen, stating that no destination drive is available.  If this happens, exit the migration and power off the computer.  Reconnect the destination SSD and reboot.  Start the migration as before, and this time you should arrive at the next screen:


Now we see a screen that is a summary of what the migration software is going to do.  It states that our Windows 7 64-bit Edition operating system partition will be copied to Disk1, model Corsair Force LS SSD SATA Disk Device, 223.5GB.  It also shows that after migration, the Corsair Force LS will have 28% of the available space in use.

The vast majority of users will not be utilizing the destination SSD’s available storage space to create any additional partitions.  This majority of users will want to utilize all of the available space for the migration.   Check that bottom box, and then click “Copy” to proceed.


Next we get a default warning that the destination disk may contain data (because we already formatted it).  Just to be on the safe side, let’s check the box and let the software do a fresh formatting.  Click “Next” to proceed.


Now we see the migration software in action!  The “Delete Partition” and “Modify Disk Patterning Style” rows indicate that the re-formatting completed successfully.  The copying of the source partition is underway.


Next we see that the copying of the source partition has completed successfully, and the copying to the destination SSD is underway.


“Microsoft Windows 7 64-bit Edition on Local Disk (C:) has been successfully migrated!”  Click “Close” to exit the migration software.  Now then, let’s go back to “Disk Management” (click on the Windows orb, right-click on “Computer”, then click on “Manage”, then select “Disk Management” in the upper left pane)  and view the partitions now that the migration is complete.


The post-migration graph shows that we now have “System Reserved” partitions and “Primary Partitions” that are exactly  proportional to the corresponding partitions on the source SSD.  The only difference is the overprovisioning area on the original  SSD.  The primary partition on the destination drive is proportional to the combination of the primary partition and overprovisioning area combined  on the source SSD. Now that we are satisfied with the results we see so far, we need to make sure that we can boot the computer from the newly-migrated destination SSD’s operating system.

Restart the computer, press “Delete” or whatever “F-key” your motherboard specifies to use during POST to enter the motherboard’s BIOS.  On our Asus Sabertooth 990FX motherboard, tapping “F8” during POST gets us straight to a small boot options window.  We select the Corsair Force LS to boot from, and in customary SSD boot speed we are looking at a mirror image of what we had / have on the Samsung 830-Series 128GB SSD.

Is our migration complete?  Have we missed anything? Would you like to satisfy your curiosity as to whether or not our migrated operating system partition is properly aligned? What follows is a pretty simple way to see proof of such:


  1. Thanks for a great review.

  2. Thanks for a great review, without which I probably would be sitting pondering over how to approach for a lot longer. Your review shed light on all (for me) relevant topics, plus ended research for software alternatives.

  3. I have a source HDD that’s bigger than the destination SSD. I know the software can handle that, since all the data fits on the new SSD. The SSD will simply have a smaller partition with less free space. But I have a question: In the migration process, will the Paragon software shrink the source partition? Also, does it really change the drive letters of the source partition, as seen in your screenshots? I’d prefer if either of these didn’t happen. Just in case something goes wrong I’d like to be able to boot from the original HDD with NOTHING CHANGED.

    • Yes it will shrink the partitions proportionally to fit on the SSD, but no changes are made to the partition sizes on the source HDD. If 1% of the original HDD’s space was for system reserved, and the O/S partition was 30% full and 69% free space, the SSD will have the same percentages used. Yes, it will change the drive letters to have whichever drive you are booting from be the ‘C’ drive. If after migration, you still want to boot from your old HDD, pick the HDD in your BIOS to boot from, and it will again show up as the ‘C’ drive. Windows always treats the drive you are currently booted from as the ‘C’ drive. Nothing will have changed on the HDD.

  4. Does the Paragon software take care of the TRIM situation on the drive being migrated to?

  5. I bought the Samsung Pro SSD and cloned my Windows 7 x64 to my Athlon 64 and it boots up in under 30 seconds now. The software is free with Samsung SSD`s.

  6. I installed the Paragon 64 bit version of OS to SSD. It appears to complete the migration process but I do not see my SSD as an option for booting in the BIOS/UEFI. Interestingly, this is a new system with a new drive. When I installed W8.1, I do not have a System Reserved partition. However, the W8.1 boots just fine from the HDD. Can someone tell me how to properly use the Paragon tool assuming that I did something incorrectly? Does the lack of a System Reserved partition on the source drive make a difference? If so, then why does my system boot perfectly without it?

  7. i migrated win7 from an HDD to my new Kingston SSD using Paragon. I boot from the SSD and all of my files seem to be where i left it but when i try to open them, they dont work. what do i do?

    • Our suggestion might be to reinstall the migrated image, or even start from scratch. Having said that, we NEVER recommend a HDD to SSD migration because their are so many, as yourself, that experience unexplained difficulties and go to the fresh install in the end anyway. FRESH INSTALL RECOMMENDED.

  8. What if I don’t have any partitions on my 2TB HDD. Can it still move the OS? Does it create partitions or how does it work? I currently have about 400GB used on my HDD and am adding a 250GB SDD

    • You have to have one partition for the OS. It simply duplicates your drive, reducing partition size of you are going from larger to smaller and there is empty space.

      • Okay, I’ll have to check again, but I think the problem that I may have is that my OS partition is the full 2TB of the drive. Will it be able to fix that or should I just re-install windows completely. I really just don’t want to re-install all of my programs.

      • So could I just create a new partition somehow and move a bunch of my files over to that?

      • This software makes an exact copy of your hard drive/SSD. You font create partitions…just follow the instructions.

      • Yes I think I figured out how to do everything I need using AOMEI Partition Assistant for free. Yeah, I think I figured out what you’re saying, but basically I had to split up my 2tb hdd into two partitions then move all the extra files overto the second partition, then shrink the first partition and clone it over to the ssd. Took a while to move 500GB though…

  9. Hello:
    My Toshiba Satellite L505-S6959 (running Win 7 Ultimate w/Bitlocker) Died and I removed the SSD from that and installed it into a Toshiba Satellite _______ that had been running Win 7 Home Premium.
    Everything Works EXCEPT I seem to have lost the Network Controller and Ethernet Controller. I downloaded appropriate Network and Ethernet Drivers to a USB and then attempted to let laptop Update with best driver (web and computer).
    Still tells me that No driver can be found.
    I cannot get to internet and it says No Connections Available………..
    I went to a computer store to see about a new laptop and the salesman said to download Paragon Migration software and use that to reclaim the network and ethernet controllers and drivers.
    However, from reading this analysis, it doesn’t appear that this is what I should do as I do not want to wipe this SSD clean. I’m not copying from one SSD to another, just using the same SSD that was in one computer and putting it in another computer.
    Any Advice as to how to get these controllers back and access the internet and WiFi?
    Any Assistance would be greatly appreciated!.

    • Your only solution is to find out what hardware is in the new laptop that you are trying to do the installation on. Aside from that, Win7 with BitLocker enabled should also pose another problem on the migration no?

      • Thanks. Bitlocker isn’t enabled right now. I found a great support site and the solutions worked for a lot of folks. However, one solution, registry edit under Local Machine, System, Network, etc… pointed out the fact that the only line of code in that Branch is the default. There should be six lines and mine’s just empty. I’m fairly computer literate but l will have to do some more study in order to I’ll have to copy the registry entries for Network from a working computer. I don’t know if this program can help with that.
