    Hi Guys,

    I've read a lot about doing this over the last couple of years and now I am in a position to complete the task!

    Here is my setup (slightly complicated as I use it for Music Production and wanted quick disks for certain files like SAMPLES etc)

    27" iMac Late 2012
    Internal 1TB 7200RPM HDD - partitioned Projects, Data & BOOTCAMP
    External 256GB SSD (Thunderbolt connection) - partitioned Macintosh HD & Spare
    External 256GB SSD (E-SATA connection via Lacie Thunderbolt unit) - Single Partition called SAMPLES
    External 3TB Western Digital Backup drive connected via USB 3.0

    You can see that I actually boot my iMAC from the External 256GB SSD connected via Thunderbolt but I want to change this setup and boot from an internal SSD.

    I have bought a 512GB Samsung PRO SSD to replace the 1TB internal HDD and have just the OS and BOOTCAMP on this disk (I have calculated that I have enough space to consolidate Macintosh OS, Projects, Data & Bootcamp on to a single SSD.).. I'll leave the SAMPLES SSD separate and external.

    I also want to CLONE both my OS X drive AND my BOOTCAMP drive as I have loads of plug-ins and applications installed and I don't fancy rebuilding the whole thing! :)

    Could you help me confirm that the following process will do this for me please?

    1 - WinClone BOOTCAMP to WD 3TB drive
    2 - CarbonCopyClone my OS X Partition to WD 3TB drive
    3 - Install 512GB SSD in to iMAC (I have all the tools and tape etc!)
    4 - Complete an Internet Recovery of OS X Yosemite to the 512GB SSD
    5 - Restore the OS X backup to the 512GB SSD using CarbonCopyClone
    6 - Create a BOOTCAMP partition (120GB)
    7 - WinClone restore my BOOTCAMP backup

    Are there any steps that are missing?

    Are there any pitfalls I should look out for on the way?

    Many thanks for any help and advice you can give :)

    Jon

    Awesome, thanks vanillamilkshake! :)

    I live in the UK so it would take time to get the iFixIt kit but I do have a set or Torx, suction pads, the correct numbered adhesive strips and some plastic smudgers... So hopefully I'll be fine :)

    Can anyone confirm if the existing HDD has a temperature sensor attached to it, and will I need to replace that when I install the SSD?

    I'm quite sure that there is temperature sensor which you technically have to replace. However, you can use software like Mac Fan Control to control your HDD fans, since an SSD will not overheat the way a HDD does. I use Mac Fan Control whenever I replace a HDD with SSD to control the fans without having to take care of the temperature sensors :)
