I have upgraded three servers and found the following difference. When I do a rug pd I get two server with just open_enterprise_server_sp3 installed but on another server I have both
open_enterprise_server_sp3 and open_enterprise_server_sp2 installed. Could I use the following to "uninstall" the SP2-related entry:

zypper remove --type=product OPEN_ENTERPRISE_SERVER_SP2

Or is there a better way to do this. I am assuming that you do not want both sp3 and sp2 listed as installed.
