Just got off of a Webex with Delphix support. They upgraded our Delphix server from version 184.108.40.206 to 220.127.116.11. It took about twenty minutes. Pretty nice compared to an Oracle database upgrade I think!
The only thing that took some time was that I had to be sure I had enough space. It looks like Delphix needs your disk space to be no more than 85% utilized to fully function. We ended up extending our four 1.5 terabyte luns to 1.9 TB each to give us space. Then I cleaned up some archive log space by running a snapsync on each source database to completion. Our system just needed a little TLC to get some space free again.
But, the upgrade itself, running the scripts and rebooting the server, took 20 minutes and was all done by Delphix support for no extra charge. Sweet.
