Thread:Project:Support desk/Problem importing from old wiki to new/reply (3)

The importDump maintenance script has some bugs, which might make it impossible to import data from an older version into a newer one (I think that might be what you are seeing). When you want to use sQlite, then I would try starting with the old wiki version (1.6.10) and use that one to import the pages. Afterwards you can do a MediaWiki upgrade to 1.22.3.

While MediaWiki does support sQlite, you should be aware that sQulite support is by far not as mature as MySQL support is. Many problems have already been solved for MySQL, while they have not been for sQlite. With sQlite you might probably run into more trouble.

If you ask me, I would stay with MySQL and do the mysqldump - mysql thing.
