Just install OSX from scratch, and you can configure the two drives to work in parallel. However, if you currently have a HDD + SSD installed (Fusion drive), then you can upgrade the HDD to an SSD without having to remove the SSD part of the fusion drive.
There currently aren’t any supported aftermarket solutions to replace or upgrade the blade SSD in the Late 2013 and later iMac’s. If you have a ‘Fusion drive’ setup, then you’ll need to split the fusion drive first and then perform the clone operation. 
Your old 2.5-inch HDD can then be housed in the enclosure.
To clone your existing OS/app setup first, purchase a cloning cable or 2.5-inch HDD/SDD enclosure to connect your new HDD/SSD to your mac, then use the Super Duper app to perform the clone, then switch the drives. Use the iStat widget to check which fan is running fast and check the associated sensor is connected properly. 
If your fans are running fast after upgrading, you may not have reconnected one of the temperature sensors properly.
No additional thermal cable is needed for all 21.5-inch 2012-onward iMacs. Follow this guide closely closely to upgrade. To upgrade the factory 2.5-inch HDD, you’ll need the general servicing kit, plus a larger 2.5-inch HDD or 2.5-inch SSD. At the time of purchase, Apple offered a 1 TB "Fusion Drive" (which combines a 128GB ‘blade’ SSD and a 1 TB hard drive), or a stand-alone 256GB/512GB blade SSD. The Late 2013 21.5-inch iMac models have a standard 1TB 2.5-inch factory HDD with a 6 Gb/s SATA port. Follow this guide closely to install the RAM modules. To upgrade the RAM in this iMac, you’ll need the general servicing kit to open it up, and your choice of RAM upgrade shown on the left.
