Q: Can I drag and drop my entire O: drive contents into OneDrive to copy my files over?
A: That depends on how much data and how many folders you have on your O: drive. If you only have a few folders and little data on your O: drive, this should work fine. If you have several gigabytes of data, doing this will almost certainly generate errors. If you have lots of folders and data, you will have a better experience if you drag and drop one folder at a time or a small group of folders at a time.
Q: Can I migrate my files from my O: drive to OneDrive from home?
A: You can but that is not recommended. In order to access your O: drive at home, you will need to use VPN and that will slow the copying of your files by quite a bit. You will have a much better experience migrating your files on campus.
Q: How long will it take to migrate my files from my O: drive to OneDrive?
A: That depends on how much data you have to migrate. A conservative general rule of thumb is if you do the migration from campus, expect it to take around 10 minutes for each 1 gigabyte of data you have to migrate. For example, if you have about 3 gigabytes of data the transfer, it should take about 30 minutes.
