I just bought myself a new SSD hard drive
Just to avoid confusion and nip it in the bud before it becomes habit, it is NOT an "SSD
Hard Drive".
There are SSDs (solid state drives) and there are "hard" drives. There is no such thing as SSD Hard Drive (although there are "hybrid" drives - but that is different yet). The "hard" refers to the platters, the actual disks inside the drive are "hard", inflexible, metallic, spinning disks. SSDs don't have "disks" or any moving parts, but memory modules much more similar to RAM modules than the magnetic media of a disk. "Soft" disks (or media) are more commonly referred to as "floppy" disks because the disks are ... floppy - very similar to magnetic recording tape, except in shape.
To your problem, I note for every SSD I have purchased, it came with migration software (or it can be downloaded from the SSD maker's site) that allows you to transfer (migrate) from HD to SSD. Or a good imaging backup program can transfer too.
HOWEVER, I would urge you to have a full backup of any data you don't want to lose.
