I reran the update of my development instance yesterday and again today
to check what has been the case actually, and was a bit confused that instead
it worked "as advertized" ... but then it slowly dawned on me.

 When testing the upgrade process I copied some DB's from the "real" instance
to my local system, but forgot to update the contents of the
"environment.permanentDirectory".  Duh, stupid me!
  I should really get used to this, but so far I didnt ...

Of course this means the update state of all the wikis (except for the main 
wiki)
has been wrong or missing. It seems the distribution manager does not check for 
wikis that are
not in the *.xed list, so they are not proposed for an update by the DM.
 But in the XWiki Admin UI something figures out these Wikis exist and needs to 
be upgraded
(btw it lists the "XWiki Enterprise - UI All" as "Invalid Extensions" then)

This must have been "repaired" itself in the lasts tests, while me restoring 
DB's and
"extensions" directories from backup. Not sure if my explanation is correct,
but it certainly is caused by an inconsistence between DB and file system.
 Which means, it is a use case that should not happen in a production system.

One final remark: in the DW I now get in step3 the option to upgrade the
"XWiki Enterprise - UI All" for every single wiki on the list, so this means
a separate click on the "upgrade" for each wiki.

 On the other hand the extension manager in the XWiki UI offers also an 
"Upgrade on Farm"
option, which upgrades the extension on all wikis on which it is installed,
all with a single click.

I find the latter one very convenient. Would it be easy to add this to the DW, 
too?
(Just an idea - if it really bugs me I could send a pull request ... but I have 
to admit
I would like to fix other things first, e.g. XWIKI-9233 )

The last step (Extensions) is displayed only if there are invalid
extensions installed, i.e. extensions that _must_ be upgraded in order
to work. So the explanation could be that either:

* XWiki Enterprise - UI All XAR was not detected by the Extension
Manager as an extension installed on your subwikis or
* the Extension Manager thought that the old version of XWiki
Enterprise - UI All works with the new XWiki version, so the upgrade
was optional (i.e. the extension was outdated but not invalid).

Do you remember if XWiki Enterprise - UI All was listed in Extension
Updater administration section under Invalid Extensions or under
Outdated Extensions?

Ah, but it did not show up for my installation; however the problem was due to 
a rogue
/META-INF/MANIFEST.MF which I somewhat forgot when cleaning up my overlay target
that should only modify a few template pages ... which perfectly explains why 
the
distribution wizard did not get invoked for me.

After deleting that file, the one from the xwiki distribution is picked up
and the DW came up on the first request for me, too.

 However it only upgrades the content of the main wiki, which has the
"XWiki Enterprise Manager - UI All" installed (in Step 2). The subwikis
have the "XWiki Enterprise - UI All" installed, however.

 In Step 3 when I am asked to update the current wiki only or all wikis,
it does not matter what I choose; the DW sends a request to itself
with parameter values action=COMPLETE_STEP and either upgradeMode=ALLINONE
or upgradeMode=WIKI.

 In my installation this causes just an empty page as a response,
which causes the DW to close and the xwiki main page to show up.
 The subwikis are not updated, but that can be easily fixed
by going to the "Extension upgrader" and upgrade the
"XWiki Enterprise - UI All" on the complete farm.

However I guess this is not how it should work ... so I should
look at the place where my overlay process has broken things a second time.

 Any pointers to what should have happened in third step?

Clemens

You're right the http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Upgrade 
was a bit obsolete. I've now modified it a bit (it probably requires a larger 
rewrite).

Now, you should know that the DW uses the Extension Manager so the information 
there was correct even though not perfect. The DW came after we developed the 
EM.

Seems you've been unlucky… It's been working well for a lot of us. Would be 
interesting to find out what happened in your case… Would have been interesting 
to just refresh the page to see if it helped.

What version of XWiki have you installed?

This is a very dangerous choice obviously since you loose any local change…

That's why you should really use the Distribution Wizard (DW) since it does a 
merge.

You must absolutely use the DW to have a good upgrade experience.

I guess this is something that looks like a bug ...
By the way, is the distribution manager expected to pop up on an upgrade?
I thought this should only happen on a fresh install.

When it comes to updating from a "relatively" old version of Xwiki,
I prefer to do it "old style", i.e. import the *.xar manually, as you did.

As you figured out it is better to exclude some pages, as listed in the
  
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Upgrade#HUpgradingwikidocuments

Additionally I think it is better to keep the "Add a new version to the 
existing document"
checkbox checked, because just in case one forgot to exclude one of the pages
one can recover from that mistake simply by revert to the version before the 
import.


I am currently preparing a migration of a rather old (2.2) installation to 5.x,
and as this installation has a lots of sub-wikis, it seems to pay off to 
manually
create an "xwiki-subwiki-update.xar" which is the same as the 
xwiki-enterprise.xar
except for excluding the Main,WebHome and the other pages which should be 
excluded
anyway.

However  I am not sure how well that plays with the application manager for the 
next upgrade
... not too well, I guess, as it might think the "XWiki Enterprise UI" app is 
not properly
installed.

Cheers,
Clemens
