I am not familiar with SQL at all and need your help. We have a server which has both SQL Server 2000 and SQL Server 2005 already installed on it (SQL Server 2005 was installed with the Veritas Backup Exec software and it does not seem to be full version installed). Currently we about to install another application (Monitoring software) on the same server which it need SQL Server 2005. What would you suggest me to do? Can I install SQL Server 2005 on the top of the current 2000 and 2005? or Do I need to create new instance on the current 2005 which it does not seem to be the full version? or what would you advice me to do?
