I'm not sure about that advice. While correct, it may not be the only way. I typically do a minimal install of the program to a new drive. Then I use my copying utility (I use a Windows machine with Total Commander, a clone of the old Norton Commander) to copy all the folders in and under /BB from one installation to another (overwriting only older files). No download needed. When I'm done, I deauthorize the old drive and authorize the new one. My installation is over 2 TB since it is the audiophile version, and I run it overnight, but even that takes less time than you describe. And some folks here use drive cloning software; I don't but it should work as well and maybe be even quicker.

Interesting you mention East West. Well over a decade ago, I bought their orchestra library and it took many DVDs. I had never imagined a program that large. Now that would be considered small.
