can ESX v4.0 and ESXi v5.0 live together ?

Hi everybody.

We have a x3850-M2 running a ESX v4.0 ... since year 2010, no problems.

Now we have bought a ESXi v5.0 license ...

Can the server boot from USB (ESXi v5) sometimes, and later boot from hard disk (ESX v4) ?

Any opinions are welcome. Sebastian.

If you put in your x3850 in the keyword box below it will show you all models with the different CPU series.

Hi,

it's possible when you only attach the one boot medium to the server that you want to boot from.

But why would you do that?

Beside if that is possible or not....why do you want to do that? That means a restart of each guest everytime you switch.

At least you should not convert the vmfs partitions to VMFS 5 as the ESX 4 won't be able to use them anymore.

well, the actual ESX v4 works fine

i want ESXi v5, but I do NOT want to ...

... erase ESX v4

... start ESXi v5 from USB

... discover something does not work

... have to reinstall ESX v4 again ...

And ESX v4 is on hard dosk, so I think I can NOT remove it ... whenn booting from USB.

Cheers. Sebastian.

Well you don't need to remove the Hardisk, it's ok to set the boot priority order in bios to USB.

Restart ?

no problem : i do run 2-3 day test with ESXi v5.

If all is OK, I erase ESX v4.

If something goes wrong, I remove USB with ESXi v5

Virtual Machines are on external disks (DS3400) and filesystem is VMFS3 ...

Then have fun!

I predict it will be good with ESXi 5, since your hardware is supported Smiley Wink

mr SCHEPP ... that was idea I had in mind, but did not know if it was possible ...

I suspect that the new operating system (ESXi v5), after booting will try to discover any discs with VM images, to fill its repository or similar.

If this operation is DESTRUCTIVE to pre-existing ESX v4 (on hard disc) then I have to forget about this test ..

And this is the reason I write to this forum ... asking for any  experiences around this environment.

Cheers. Sebastian.

mr SCHEPP - I am spending some time searching for "supported hw" page ... and you see to have it .

Can you provide any URL indicating my hardware is supported by ESXi v5 ?

Thanks. Sebastian.
