We are going to start the process to upgrade from Informatica 6.2 to 7.1.1. We do not have any extra client machines to install the 7.1.1 client on. Am I able to install both Informatica clients on the same machine? I know when upgrading from 5 to 6 we just changed the win.ini file to change between the different versions installed on the same machine. Can this be done between 6 and 7? Thanks
