XCPNG 8.3 availability?

SylvainB

Thanks Olivier, if I accept the risk, how can I upgrade from 8.2 to 8.3 beta ?

olivierlambert

Just insert the ISO, boot on it and follow instructions This will even backup your previous 8.2 install in case you want to move back.

@olivierlambert Thanks !

I may have missed it (been out on vacation and then got COVID so I've been absent from the forums )

But is 8.3 going to be upgradeable in place without using the ISO on official release or is it still going to require the ISO upgrade method?

Going to upgrade my entire lab to Beta 2 as soon as I can to get testing with some things, will just use the ISO for that, but thinking about my production installs.

olivierlambert

You mean 8.3 beta to RC to final with yum?

planedrop

@olivierlambert Apologies, I should have explained better.

I mean from 8.2.1 to 8.3 once final is out, using yum instead of having to use the ISO to install.

Basically, using XOA to install the update like I would normally update a host instead of using the ISO.

And again apologies if I missed it.

8.2 to 8.3 will be only ISO upgrade supported, since it's far less risky. Doesn't mean yum won't work, but it won't be officially supported or tested

@olivierlambert Will 8.1 to 8.3 upgrade path also be supported?

olivierlambert

Via ISO, the upgrade should work too, yes

planedrop

@olivierlambert Makes total sense to me, just wanted to be sure.

Excited to upgrade my lab, should have done it with the first beta but just hadn't found the time.

Thanks!

Actually, I'm going to make it impossible, on purpose, because it won't give you a clean and supported 8.3.

However, there's still the alternate upgrade method using the ISO which doesn't require to boot it: https://docs.xcp-ng.org/installation/upgrade/#using-the-installation-when-you-cant-boot-from-it-remote-upgrade (once we have fixed a remaining issue with this upgrade method in 8.3).

It will work, and we will test it internally, but be aware that it will not benefit from the big amount of QA made by XenServer for XenServer 8, because they only guarantee 8.2 CU1 => 8.3.

8.1 fully updated => 8.2.1 fully updated => 8.3 is a safer route.

I don't expect any issue outside maybe very specific situations, for the 8.1 => 8.3 upgrade, though.

If someone is already rocking and testing 8.3, what would be the best way to update?

A. Fresh Install 8.3 with the ISO
A.1 Afterwards importing configuration backup?
B. Update 8.3 beta with 8.3 ISO Upgrade path?

stormi

@Houbsi B. This will give you a clean system but will keep your XAPI database, SRs, VMs, etc.

@stormi Is using the ISO the only way to go from 8.3 Beta to 8.3? Will there be a patch/update path?

stormi

@CJ yum update from 8.3 beta to 8.3 will be possible, but I still recommend using the ISO. In a perfect world, yum update would give you exactly the same result, but in reality there are always corner cases where files or packages are left behind (we have no sane way to tell yum/rpm to remove an installed RPM, unless making another RPM obsolete it and thus make it impossible to reinstall later if someone needs it for a good reason).
