Client asked about downtime. He wanted some solution. I already told him that this is not possible. i told During the upload site will remain down.... At the end Client should be cleared about what he wants in limited resources. So he is now. i raise this thread in group because i was thinking may be i am on mistake (In terms of some concept). There can be some way to do this.
