Chrome Sync:
We spent some this after their training setting up Chrome Sync for her. I realized that teachers first thought is to sign in to Chrome on their new laptops which is what Cathy did. However, in order to have anything to "sync" she needed to sign into Chrome on her old laptop first, click Yes, to sync the data, and THEN sign into the new laptop.
Google Drive and MS Office (and more):
While teachers can use the Data Migration Tool to transfer their files and folders from their old laptop, I have heard a few say they wish they hadn't done it because it brings everything over - even some junk they didn't want. Another option for teachers is to create a folder, drag their desired files and folders into that one and then up to their SAN folder and then drag it down to their new computer.
When you do download drive to your desktop, you'll log into your Google Apps account and a Google Drive shortcut will appear on your Desktop as well as in your folder structure in File Explorer.
Every time you connect to a network, your Google Drive will sync and your files will be updated. You aren't limited to only Google files either! You can also save your MS Office files, your pictures, your flipcharts, etc. to Google Drive.
This video from Google Gooru provides a quick explanation of how to save your MS Office files to Drive.
