Currently we are using 4.3.9 version winscp to SFTP the files.
We use username,password and hostkey to connect to server via SSIS package 2005.
Host key = ssh-rsa 1024 XX:XX:XX:XX:XX

Our client has requested to change the 1024 bits host key to RSA 2048 bits.
Can you please tell me how to generate the 2048 bits host key in the same winscp 4.3.9 version and please let me know if any setting changes are required for 2048 bits host key.

This is server's hostkey. You cannot change this on client-side (WinSCP), you need to change it on server-side. And obviously as the hostkey is global, you need to notify all users that use the server.
