Moving Apps from 1 HDD to Another

My current computer setup:

Hard Drive 1 C:\ : SSD, OS only, and a couple games.
Hard Drive 2 D:\ : Applications, Temp Folder (Windows Temp Folder), System Folders (My Documents, My <x> folder, etc).
Hard Drive 3 E:\ : Media (Everything else).

Hard drive #2 is getting a bit older. I already had one drive crash, and it was a newer drive than even HD2. I was wanting to move all my apps, to a brand new drive (Hard Drive 4), and make it the D:\ Drive again. That way, I didn't have to uninstall all my applications, and then reinstall them all, and set them all up again.

I figured I can just copy over everything and I should be fine? The steps I would take:

• Install Hard Drive 4 (F:\)
• Copy All the Apps to the Hard Drive 4, Keep same File Structure
• Change Temp Folder to E:\
• Change System Folders (My Docs, etc) to E:\
• Reboot
• Turn Off Computer
• Take out Hard Drive 2, and move Hard Drive 4 into same spot as Hard Drive 2
• Turn On Computer
• Disk Management -> Change Hard Drive 4 into D:\ Drive
• Change Temp and System Folders back to D:\ (Hard Drive 4)
• Reboot

Am I missing a step? Or is there an easier way? I just want to replace Hard Drive 2 with a new Hard Drive without reinstalling everything. Thanks in advance.
