Hi Narasimha,
The ATL of 3.2 may not fully work with 4.x. So follow these steps -
a) Create a DB/repo (say R1) in the new server or location.
b) Install the 3.2 ATL to the new DB (R1) location.
c) Install 4.x on the new server
d) Create a local repo from repo manager with R1 as the new local. While creating, in the repo manager choose R1 and click 'Upgrade' option instead of 'Create'
Hope this helps.
Arun
