I see the following link
Novell Documentation

It only lists.

Database Version
Microsoft SQL Server 2008 R2

Oracle 11g R2

Sybase SQL Anywhere 12

Is this means Novell saying they only support "Microsoft SQL Server 2008 R2" and they don't support Microsoft SQL Server 2005 any more on ZCM 11.1?

This would means every one will have a big issue as it not supported 2008 R2 on current version of ZCM Servers and migrating all ZCM servers to 11.1 will become a big issue
it also chicken and egg issue which you need to do first?
