Ender,
Thanks for posting about running 5.5 and 8 on the same computer. I was about to attempt this as I beging migrating to 8. I have an Xserve G5, however, with dual ethernet ports. Even though you've said you can't run both on the same computer, do you think it would be possible to do this anyway if I assign one IP address to Server 5.5 and the other to Server 8?
Thanks
