Hi,
I have an existing XWiki enterprise 1.3.1 running with a mysql backend
and storage version 7351. I would like to upgrade to XWiki enterprise
2.6, but I am running into problems.
- a xar export eats all ram, and the max heap is already the maximum
of my 32-bit linux (-Xmx2600m) . When I increase it the jvm fails to
start. The backup.xar stops at around 1.1GB, and then I gets
OutOfMemory execeptions all over the place.
- when I install 2.6 using the same mysql backend, the storage
migration throws a massive amoutn of errors, mostly due to "Exception
while saving object XWiki.XWikiUsers". This is migration
R15428XWIKI2977.
Is there a way to perform an offline migration, so I can debug where
needed, ot a way to perform an export and import in a clean database
offline?
Regards,
Leen

The XWiki team has recently, and successfully, migrated our plain old XE
1.3.8295 farm to a new XE/XEM 2.4.30451 farm. A couple of seed documents
have been born from that project:

http://ebiotic.net/bin/Draft/MigrationCheckList
I think that at least one of them could be moved to a convenient place
in the xwiki.org farm, but I've had no time yet to follow this thread.
Perhaps they could be useful for you even in their current state.
Also, I must update this installation to the current available XE/XEM
release. I think this page could also be checked to see how the XWiki
team is getting XWiki farm updated!

Hope this helps!
