Before going on to the compatibility of NetBackup Software, are you familiar on the components you handling?
1. What is the role of the NetBackup Appliance?- If is a Primary (Master) Appliance, have you consider also the pre-requisites of Primary...
Hmm... Seems like this query was from quite sometime and no one answered.There isn't flex 8.3 instance release likewise for NBUA. With reference to the SCL, it is compatible with 8.3 master with media that is 184.108.40.206.Hope this helps.
Very sadden to hear this news. I can vividly remember reading Marianne advises on workarounds to resolve issues at NBU 7.6.x when I first started doing NetBackup. She will be dearly missed by the community. RIP Marianne.Regards,
