SSD upgrade for MacBook Pro 13" Mid 2012

MacBook Pro - MacRumors Forums - forums.macrumors.com

Hi,

I use a MacBook pro Mid 2012 13" inch laptop. Detailed specs are given below.

- 2.9 Ghz Intel Core i7

- 8GB 1600 Mhz

- 1 TB HDD

- MacOs Sierra

I am thinking of upgrading the hard drive to an SSD and use the HDD in the optical drive as secondary storage. My plan is to install the MacOS on to the SSD, with the applications an document files installed on the HDD. Is this possible ?? I heard this gives faster performance.

I have tons of software currently installed on the 1 TB HDD, there are also several Virtual Machines installed as well , the disk is currently using 400 GB, do I have to clean install MacOS on the SSD ?? what about activation etc.??

I have seen some videos on ifixit and it seems this can be done. I have selected on the following parts for this.

- SSD

-Drive Caddy
