Is it possible to take my current SSD and put it in a new build, thus transferring all of my data? Or is there a manual process involved?
Basically yes, however you may encounter problems getting the operating system to accept the new hardware. Unfortunately many copies of Windows (as an example), are locked to your hardware meaning that you have to buy another copy of the Windows license in order to use Windows with the new hardware. These types of software/OSes are known as OEM and are licensed to be used on ONLY one machine and cannot be "deactivated" or repurposed for another machine. Depending on circumstances (usually how different the two builds hardware is), Windows may think you need a new license when moving the SSD over to the new machine. Your files will still be accessible, etc. But Windows may no longer be activated. Similarly, other licensed software (eg: Adobe Suite, Microsoft Office, etc) also use similar solutions to Windows OEM to deter software piracy and you may also end up with similar problems.
All of that being said, its probably a good idea to perform some "spring" cleaning (doing things the "manual" way) on your SSD and just backup all wanted data to a removable harddrive or usb drive first, and then reformat the SSD entirely for the new system. Reinstall Windows (or whatever OS you're using, linux, etc) from scratch and then move the backed up data back onto your SSD once you've finished updating your OS and installed necessary programs/software on it. This will help purge any lingering software issues from the previous build, free up space taken up by old drivers, and usually give you a better experience over all.
You may find some of these tools helpful in getting a new build setup:
Windows 10 USB Install: https://www.microsoft.com/en-us/software-download/windows10 (for getting the disc image of Win 10)
Rufus: https://rufus.akeo.ie/ (for making bootable usb drives, I recommend this since the Windows 10 Download tool often just plain out just sucks and doesn't work).
Linux Mint: https://www.linuxmint.com/download.php (Want to try out linux? This is probably a good newbie distro to try out.)
Ninite: https://ninite.com/ (Install all the free software at once without having to run each installer individually).
This is extremely helpful, thank you very much
I’ll probably backup onto external hd, and then reformat ssd.
