how to upgrade my current OSX, apps, personal files, etc to a new brand SSD

If you have the old hard drive, buy an enclosure, boot your computer off the old hard drive, make a clone of your old hard drive and then copy the clone to the SDD. That will also give you the old hard drive for additional storeage. Other World Computing sells enclosures.

Other World Computing

Clone - Carbon Copy Cloner (Often recommended as it has more features than some others)

Clone – Data Backup

Clone – Deja Vu

Clone - SuperDuper

Clone - Synk

Clone Software – 6 Applications Tested

Prior to any cloning or data transfer, remember to open Disk Utility>Erase and format the new SSD to Mac OS Extended (Journaled).
