Hi Srinivas Kullakanda, which version of 11.4 you are using? There was a major change in the encryption standards in the 11.4 SP1 release and if you are still using the prior versions, you might end up having the mentioned defect. You can contact support for the latest copy of the TI.exe file, which has the issue fixed.

I resolved this issue by uninstalling the application on the new server and started with the oldest version, imported data and then upgraded to the SP1.
