I'm just trying to upgrade from SLES 10sp1 to OES2sp1. During the process of upgrade, I added OES2sp1 iso image as add on product. when it started performing update, it ask me for SLES10sp2 iso image. After completion SLES update it should ask me for OES iso image(?) but it didn't ask me. It directly going to Network config. There I got the following errors one after one when I click next
inst_check_ip doesnot work
inst_oes_preconfig doesnot work
inst_oes_edirectoryconfig doesnot work
inst_oes_postconfig doesnot work

after completion of upgrade, I checked the server, its got only SLES10sp2 but not OES2sp1. Any one have an idea.
