BRRABill's Field Report With XenServer

I happened to notice in XO the following...

(xo-web 4.16.1 - xo-server 4.17.0)

Should those be the same? I was pretty sure they were both the same the other day when I upgraded them.

Danp

@BRRABill No, they can vary depending on the release schedule. My production server is currently (xo-web 4.16.0 - xo-server 4.17.0)

OK, I am set, then!

Also upgraded one server (of two) to XS7 tonight.

Just remember that migration from XS6 to XS7 is a one way operation.

Why would one ever want to go back?

Danp

@BRRABill You wouldn't downgrade from XS7 to XS6. However, with one XS6 server and one XS7 server, I could seem someone wanting to migrate a VM between servers and not be able to if the VM resides on XS7.

Indeed, you can't live migrate a VM from a recent version of XS to an older one.

But you can go the other way, thank goodness!

Would really suck if you couldn't. Nice that updating isn't too bad.

I was certainly happy to have XS installed on USB.

I wonder what it would be like if XS is on the same disk/array as the SR.

BRRABill

Has anyone ever done an upgrade to the same version?

By that, I mean, installed, say XS7 over an existing XS7 install?

I am thinking of doing that to test my "clone to a bigger USB" theory.

BRRABill

Another question, this one more for general knowledge.

If I were to clone the current boot USB, and then try this upgrade and it bombs, can I just go back to the cloned original setup?

This is the kind of stuff that I don't think you can do, but then @scottalanmiller says ... "you are thinking windows ... Linux is just .... EASY"

Yes you can do that. As the Boot USB is what is running the hardware, the hardware doesn't store any of the boot info.

And none of the VM info/data is altered with an upgrade?

So, in theory you could try going to 7 from 6.5, it could bomb, and you could just go back to your 6.5 USB?

That's the theory.
