BRRABill's Field Report With XenServer

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

Of course, testing in a LAB would be ideal.

What, no one has ever tested this?
Once I get all the production stuff up I will give it a shot.
-
Testing is for losers.

Or for people who prefer to not play with production.
But YOLO!

What about move and copy? Can you do that to a stopped VM?
What about export? Could i export the VM from XS7 and import it to XS6.5?

I don't believe you can move a VM backwards to an older version of XS7.
-
@BRRABill You should be able to export / import from XS7 to an older version. Not sure about moving a stopped VM.

I admit I am still unclear (as are a lot, I think) as to how much the VMs get touched in various operations.
For example, my question yesterday about a botched upgrade. If you can theoretically go back to 6.5 from a botched 7 upgrade, it can't be touching the VMs, right?

Well if the install was botched, then perhaps the upgrade to the VM's hadn't happened yet.
The only thing I recall changing when moving from ESXi version to version was the ESXi tools inside the OS, the outside (the VM container) didn't seem to change.

Ah, OK.
Can you perhaps invent a little paper clip that comes up on the bottom of the XO windows that tells you to click that button again?
I AM KIDDING, OF COURSE.
BTW, I know you guys watch Silicon Valley. What a coincidence I mentioned this, haha.

So, for reasons I am not going to discuss to protect my stupidity, I reinstalled XS7 today.
I started from scratch, and this is how things got partitioned on my fancy new 64GB USB stick.
