EDIT/UPDATE: Nevermind my advice, as you already wrote that you know to redirect.
I have posted in some other thread how to create a junction / link to another drive. To the OS it will look like the db file resides in the appdata path but in fact it is somewhere else.
I use this constantly to place some steam games on SSD while my steam data folder points to some other harddrive.
Here's a link for an easier to use GUI:

But maybe try it out first before attempting the real modification, so nothing will go wrong
