One solution would be to install a 2 machine cluster running Solaris 10. The 2 existing physical machines can be converted into "branded zones" - one running a Solaris 8 brand, the other running a Solaris 9 brand. Alternatively if the applications and database software support Solaris 10 then they can be installed directly on Solaris 10. The product names you want (to help find the documentation) are "Solaris 8 Containers", "Solaris 9 Containers" (containers are zones plus resource controls) and "Solaris Cluster". Any of Sun's modern range of servers would be ideal for this. Also consinder redundant power, UPSes, NICs etc. As well as bigadmin (which is largely unstructured) there is also docs.sun.com which containers the official Sun documentation. The product pages on sun.com should give you the level of detail you need for this exercise though, hopefully. HTH Andrew. -- This message posted from opensolaris.org
