Is it safe to install Seafile with script and connect existing DB and data?

I use Seafile for several years. Till now I maintained it in old fashioned way - updated, maintenance etc.
From some time i see that i would setup everything a little bit differently and one evil idea came to my mind.
Why no to install Seafile from script, to make it easier and 6.3.7 compliant and just to put details of my DB and map network drive?
Will it work?
What are the chases to destroy existing DB and data? Yes i will backup whats possible, but just asking.

Normally, this should work. But why not just change the config?
