I plan on installing my new SSD but I have a few questions. I'm running el captain, should I upgrade to the latest OS and make a time machine backup, install the new SSD and boot from time machine? Will the image (46GB) be a full copy of the OS and be able to copy to the new SSD? I have Microsoft Office that I'm trying to keep. My other option was to download the installer, make a bootable flash drive and install a fresh OS and then copy whatever I had from Google Drive or something, but I'd lose Microsoft Office. Let me know please!
