Switching OEM Windows 8.1 to SSD, any advice?

Hi All,

I have the ThinkPad Yoga, i5, 512GB 5400rpm + 16GB SSD for cache. The system is really snappy but it does take some time when moving big files around or in the rare cases I restart it.

So, I decided to upgrade to a Samsung 840 EVO 500GB which seems to be a very good choice by looking a reviews and tests.

My questions are:

  1. Has anyone tried to migrate the OEM Windows 8.1 installation to an SSD?
  2. How does it work now that the key is in the BIOS?
  3. Does the included Samsung Wizard do the job or another migration tool is better?
  4. Any tips for ensuring a smooth transition?

Thanks all in advance for your tips!
