Upgrade NBU from 220.127.116.11 to 18.104.22.168, with some client-server using 22.214.171.124
Im planning to upgrade my NBU environment, from 126.96.36.199 to 188.8.131.52.
Master Server: Solaris 10. NBU version 184.108.40.206
Media Servers: 6 servers, 2 W2K R2 and 4 Solaris 10. All at NBU 220.127.116.11
Some client servers with 18.104.22.168 (because those are windows 2012) of course I know this is not supported by Symantec, due Master/media are lower than client version. But im just bit courious whats going to be happen, when the upgrade time, with the metadata images migration.
Should I open a Symantec call? Or should I revert the client version to 22.214.171.124? What could be the worst case?
Comments, are very welcome.
