Timeslips 19 Question

I am an IT tech and one of my clients I am moving from Timeslips 15 to Timeslips 19 .   I am putting them on 2 different servers because they for some reason want to compare the two databases.   Timeslips 19 will be run on a new Hyper-V SQL server I setup and installed.  Anything I need to be aware of before doing the install would be much appreciated.  Also looks like Timeslips uses a mapped drive to work properly.  Is that a requirement or can I us a direct path to the Server?  Which is best?  Thanks for any advice you can give me.  This is my first client that uses Timeslips so all new.
