I have a doc from Doug M. from 2008 discussing zero downtime upgrades. " With the use of a parallel server and database and using the Distributed Server Option (DSO) technology, an environment can perform an upgrade of the AR System server while providing continuous availability. There is some very specific additional work involved, but it will offer a reliable upgrade without data loss or service interruption. "
Don't know if it's still current, so don't want to post to the whole list unless Doug says it's ok. I'll check with him.

You needed a server group, you make all of your changes, all of them, to include deleting columns, etc. You can connect to the admin server in the server group to see the changes, work with the new workflow, everything...the users remain on the other node(s) of the server group and never see the changes...everything stored in the same db...then when all of your functional testing is done you literally 'flip a switch' and the other nodes in the server group arsignal, get the new cache, and it's 'in prod' At that point all that is needed I believe was a Mid-Tier cache flush, and the users were using the new forms/workflow 'in an instant'... You of course still need all of your planning, testing, etc...but the zero down time part was for the user. All of the work could be done during business hours, no late night, evening, weekend work to get the new code in place...it can all be done next to the current stuff...it was an amazing demo.

It may be possible with months of planning, but more than likely you will still have some amount of downtime. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG<mailto:arslist@ARSLIST.ORG>] On Behalf Of teresa S Fannin Sent: Tuesday, July 16, 2013 11:57 AM To: arslist@ARSLIST.ORG<mailto:arslist@ARSLIST.ORG> Subject: Re: 7.6.04 Upgrade to 8.1 There was that discussion at last year's rug where they pointed production to their failover area. Did the upgrade in production while everyone worked from the failover area and then switched back when the upgrade was complete. More steps than this but you get the idea.

I'm going with the conspiracy. Nah, just kidding. Must have been something I inferred from the overlay enhancements in 8.1. Darn.

I know that 8.1 wasn't released at last years rug, it was just 8.0, but I know that after the RUG David posted an idea (https://communities.bmc.com/ideas/1421) that is in a status of 'Under Consideration'....when they are available, it's changed to 'Delivered'....so all of the facts that I have currently available tell me that the demo we received last year isn't in a current code line...but if you could point me to docs to the contrary....I would love to see them.

It's something R&D is working on for the future. They wanted to see what kind of feedback that would have as sort of a litmus test. I could be wrong but that was my takeaway. Doug M was in that session and maybe he can go into more detail.
