What happens with VTS when I upgrade LR? ...

At 12.50 patch 3 now. About to install LR 12.53 over the top.

But on two of the machines I am using VTS and have a large volume of data in each.

A couple questions:

1. When I run the 12.53 installer over the top of 12.50, will VTS also be automatically upgraded? Or do I need to run the VTS installer separately?

2. What will happen to my VTS table structure and data when I run the LR 12.53 or VTS installer? Will it be retained?

Thanks in advance,
