Hi,
in our company we used the standalone version of XWiki for testing and are
very satisfied with it so we want to migrate to the new version and a more
robust setup.
The setup is Windows Server 2003 R2 (sadly only 32 bits) with Apache 2.4,
MySQL 5 and Tomcat 7.
XWiki 6.3 is setup now including a Wiki Template so I'd like to migrate the
data I exported as XAR from the 5.4.5 standalone instance.
My approach was exporting data from 5.4.5, creating the Wikis using the
template and importing the spaces and pages from the XAR export.
The issue I'm facing is Java heap size which constantly gets in my way. As
we're on a 32 bits system I can only assign ~1.2 GB of memory (the server
has 4GB).
This limitation makes it impossible to import the data into the new setup.
I tried general export/import via administration page and the various
options using the Admin Tools Application but on one of both ends I always
get the out of memory error.
- Using normal export/import: Export works but import throws the error
- Admin Tools - Export pages and spaces: Export works but import throws the
error
- Admin Tools - Large Export on Disk: the heap size error is thrown
Quite frankly the one in Admin Tools should change it's name since
it's far from supporting anything close to large...
Do you have any suggestions/hints on how I can migrate the spaces and pages
I have in the 5.4.5 setup to the 6.3 one?
The extensions that have the less memory footprint (probably by far) I
can think of are
http://extensions.xwiki.org/xwiki/bin/view/Extension/Large+Wiki+Export
and http://extensions.xwiki.org/xwiki/bin/view/Extension/Large+XAR+Import
so you might want to try them. Note that at least for export it's
fixed in 6.2 but for import even if it's been improved a lot the way
the UI work you still have to be able to attach your attachment.
Thanks in advance,
Dennis
