WARNING: If you try to reboot to the recovery partition, Disk Utility will see the newly-installed SSD as "half of a fusion drive" and try to "repair" it back into a fusion setup with the existing HDD. In the process, it will WIPE OUT all your previous data (on the HDD).
My suggestion is this:
1. Boot from the (old) HDD drive.
2. Launch Disk Utility
3. Initialize and test the new SSD drive
4. Get ahold of CarbonCopyCloner from here:

(Note: even though it's "pay for" software, you can download and use it FREE for 30 days)
5. Use CCC to "clone" the contents of the HDD to the new SSD
(Note: if you don't want to clone everything, CCC will let you "pick and choose" -- you should at least clone the system and your personal user accounts and apps)
When done, you should have -TWO- bootable systems -- one on each drive.
I suggest that you KEEP a system on both drives. You never know when you may need to do an "emergency boot" from a source other than your "main drive". It's especially nice to have this ability to do random drive maintenance, etc.
