Clone to Higher Version

[She Sull]

So we're participating in the Eureka Early Access program, but we don't want to upgrade Prod before we play with Eureka in Dev. With that, if for whatever reason we decide we can't upgrade Prod at this time would we be able to clone Prod to Dev with Dev being Eureka and Prod being Dublin (will SN downgrade Dev)? Or do we just have to upgrade both and hope for the best?

I know the Wiki states the instances have to match and that it would automatically upgrade the lower environment, but how does this work in my situation where the lower environment has the latest release?

Thanks,

Hi Sherry,

I've been involved in some upgrades. The path usually taken is to clone Prod to Dev and then upgrade dev to any version you want.You can run the test scenarios in Dev/ Test which ever environment you decide to do it on. In case any defects are found develop the fixes in dev and capture in update sets. Once you are sure of everything , then upgrade Prod to Eureka and apply the update sets of any defects that you fixed.

I hope this helps!

Thanks, Avneet.   That's pretty much the plan I have in place I just felt I needed a back-out strategy, or at least identify this as a risk, if for whatever reason, let's say my manager decides we can't upgrade Prod to Eureka yet. I didn't think I could downgrade an instance to an earlier version, just wanted to be sure.

I appreciate the feedback!

Hi Sherry,

What we used to do is, first upgrade the dev instance to the latest version. Once we figured out all the issues, we would fix those and capture that in an update set.

Then we would upgrade the test instance and once the instance and midservers are upgraded, we will commit the update set. New version is tested again in this instance and any fixes to be done are made in dev instance and moved to test instance via update sets. This way, by the time it moves to prod, we would have a solutions for all the possible issues with this upgrade.

If you want to have prod cloned and upgrade tested on the clone, I would recommend that you request ServiceNow for another instance, clone that instance with prod and then do a round of testing on that instance after upgrade in Test instance is complete.

Hope this helps.

Thanks & Regards,

Hari
