I have a larger Prod DB on approx. 450 GB
I would like to make a new Sandbox as a copy of Prod (and then get developed a tool to delete transaction data so only one month data is avalible after).
I do not have extra capacity todo the first step. My question is what will happen if I do above senario. Will it allow me todo - how long will it approx. take - will it impact my PROD (speed).
