It has no advantage ,none of your smart blocks,calendar information etc is store and can be restored.Unless you like headache
Its is best you start fresh if some thing goes wrong.nothing of significant is store in the database
I have installed airtime on a machine some 2 years ago and all the reasons like corrupted database have never occurred and you are not dealing with any need for separate database.One Airtime install serves anywhere like thin client architecture
Just raid your drive and one goes out replace it and you are good to go
Anyone reading this a find it funny about my grammar , I make no apology ,Go get a translator. "The Problem with education today is that it takes a university degree to switch on a light bulb" "You learn from your mistakes but wise people learn from others mistakes avoid Making mistakes there is not sufficient rooms to make them" "Innuendo","If's","Assumptions" and "Fear" are for politician.Who,What,where,When and How are for those seeking knowledge and care about Humanity. "I might be in Mud but that does not Make me a Wild Hog(pig)" “Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage to move in the opposite direction.” "The only thing that remains constant is change itself" May the force be with you,until our path or destiny bring us in tandem.
You don't want to even try. The best solution is to install it to a vps that has imaging capabilities and to start fresh whenever possible like voisses mentioned. Sorry...
