Yes I tried it ...It was not working..
But yes friend I managed to solve it..
The problem was that there was no route present between the servers.. so when I was trying to cpoy one domain at time it was showing timeout error.
Then I tried all ,so it also didn't work...
When I tried to scp,ftp,ssh from old to new server it also went in mess..
Then I added route from old to new server..
It worked fine..
And yes there are 388 domains on server...
it is very time consuming to copy one by one...
