LiveInstall Solaris 11 from Solaris 10
By unixman on Apr 24, 2012
Oracle Solaris 11 includes a number of key improvements, many of which fundamentally address lifecycle management and patch management challenges present in older versions of the operating system. This continues to be one of the big reasons customers are upgrading to Oracle Solaris 11.
A number of our big customers had previously expressed interest in being able to get onto Oracle Solaris 11 while leveraging their existing Oracle Solaris 10 installed base and related Live Upgrade technology, particularly in the context of now more-than-6-year-old T-series and M-series SPARC systems. Because of how traditional LiveUpgrade technology operates, and the realities of newer modern infrastructure requirements no longer being satisfied by the (now aging) SVR4 packaging subsystem, we've had to ensure that what we offer in deployment capabilities of the system would, now, more closely be in tune with newer demands of today and tomorrow; two of the goals being to offer consistency AND provide for reduction of cost for both - deployment and maintenance.
Elements of our work involve introduction and blended integration of some of the newer technologies like Image Packaging System, Automated Installer, Service Management Facility, newer System Configuration and ZFS root file system. Although this has posed some operational challenges in being able to leverage traditional as-is LiveUpgrade to migrate from Oracle Solaris 10 to Oracle Solaris 11, we did listen to our customers who took the time to talk to us about their interests and needs in this space. To aid in the process, we have published a how-to article that allows customers to follow a LiveUpgrade-like methodology in getting their existing Oracle Solaris 10 system to Oracle Solaris 11 while minimizing risk and still being able to boot back to Oracle Solaris 10 if they so chose. This is particularly of interest to those who have grown to appreciate the value that LiveUpgrade delivers. Here is an illustration of what takes place (click to zoom in). We define an archive system and a migration system. I encourage you to fully read the article (from our growing library of how-to articles) and let me know your thoughts.
