Hi all,
as anyone can see there's a first attempt to upgrade from v0.9 in
http://www.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgradinganXWi…
The problem with this approach is that it just migrates the Java code,
but not the one inside the xwiki pages stored in the database.
In order to construct a strong and complete migration process I need
some help (as usual :-D), mainly :
* what pages/spaces contain code that is considered part of XWiki
distribution ??
* does anyone has success in making the code at
http://old.xwiki.org/xwiki/bin/view/Test/ImportExport work on 0.9 ??
* any other places to look at for other pieces of XWiki core that should
be added to the upgrade guide ??
Thx

If you're talking about XE (XWiki Enterprise). The list of pages is
available there:

I think we need more detailed instructions for moving data from an
existing DB to a new DB. The exporter would be the best way to do
that but importing a large XAR doesn't work either when the memory is
not large enough so import at the DB level is required anyway for
some large XWiki installs.
I haven't tried doing this myself (I don't have a 0.9 wiki to
migrate) so I'm not the best placed to help here but I'm pretty sure
some 0.9 users are having a hard time so they should speak up!
Have you checked the list archives to check messages about migrating
to 1.1.1 from a 0.9 install?
Thanks for doing this and helping out!

You will see of couple of messages of mine ;)
With time I came close to migrate and I documented how I did it in these
messages. Mostly the information is available in the Wiki as well but it is a
long process to identify what we need and to fetch the information. For this
reason this list is a good start but we could also get together on xwiki.org
and build a page just around the issue if it makes sense.
I don't have the migration done yet, so I am angry for any info you could
produce ;)
To make the story short you have to find this information:
- install the import/export into 0.9 (see old.xwiki.org for the code)
- fix the database XWD_ARCHIVE mediumblob type to longblob (xwiki.org)
- increase the attachment file size limit (also xwiki.org)
- increase the heap size used by your servlet container (-Xms : see for
example http://java.sun.com/docs/hotspot/gc1.4.2/ for more)
Weirdness and bad luck:
- (A) migrating to 1.1rc2 works to 1.1.1 fails :P
- (B) 1.1.1 can't open the xar package (once attached), it complains about a
file not ending correctly (zip)
Strategies
- option 1 - install 1.1.1 fresh and import a xar (first fix the issues above)
- option 2 - install 1.1.1 and connect it to the database (there bad luck
happens)
Possible ways to fix the problem
- B could be fixed by modifying the import code (is there something hardcoded
involving the size of the expected zip?)
- the database migration could be fixed by running a script within mysql to
migrate the schema (if only we knew what has been changed as well as the
exact meaning and purpose of the attributes)
What's next?

I think that all of these are documented in the migration process from
0.9 (sorry, it's a bit la te here, I'll take a look tomorrow in the
morning).
BTW, if you find any error don' t hesitate in correct it, and *please*
don't use th WYSIWYG editor because it has problems with some tags.

The problem si that XWiki core isn't just Java, it also contains code
inside the XWiki pages. e.g. if I install a new servlet container (with
XWiki 1.1 inside it) and a new database where I copy the old one, this
installation has new Java code and old wiki code. A typical example is
the page that generates the RSS feeds (RssFeed, I think)

I think that after that Export Import work it' s piece of cake. Two of
the three main pieces are already easy to migrate (code and skins), we
need only to extract the pages that are not part of XWiki code from one
database and put it in the new one !!!
Enjoy !

The problem with this comes from XWiki having code at the page level, so
if we make a bulk copy (as in the instructive) not a complete upgrade is
made.
My feeling is to let both migration path coexist so that anyone can
choose which one to use (I'm not sure this is a good idea, but in the
meantime the database copy is left into the migration path)

Apparently you got to that part.
Applying the fixes/patches first to the 0.9 database may help the export
script. That's just an hypothesis. Anyhow something made it work in my case.

I beg to disagree here. The import feature (in 1.1.1) has issue with reading
XML files such as the descriptor in the xar package :(
