I have been using EOC 1.6 for years. I am very pleased to see that it is finally getting some love. That said, I read that 1.6 and 2.0 can be run in tandem but that a new server would be needed. Is that actually the case? If so, why? I would much rather install them on the same server so that when I am ready to cut over to 2.0, I would just need to change the website bindings. On a different server I would have to either do an IP/name swap or multiple DNS record changes for the SSL certs.
