You have to increase amount of RAM for your JVM process. See http://www.xwiki.org/xwiki/bin/view/FAQ/HowToSolveAJavaHeapMemoryError If you have a big .xar to import, you may have to: * export your source wiki space-by-space (see http://extensions.xwiki.org/xwiki/bin/view/Extension/Large+Export+By+Space+A...) * split your .xar manually (unzip/edit packages.xml/zip part of dirs - risky if you have weird page names) * use some BIG machine (I've used EC2 High-Memory instance) Cheers, R.
