Nick, Half of your answer is here: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/pdf/Installation_Guide.pdf That's pretty cut and dried. I don't recall ever seeing 32-bit to 64-bit upgrades discussed in Red Hat documentation. That may be because it's considered one of those "They want to do what?" subjects. :-) --Doc _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
