I'm working with a group that has customized their mediawiki installation so that they can create multiple wiki instances, each with their own database, that have no knowledge of each others existence. This was done for security and privacy reasons.
The dumpBackup.php utility seems to be built for a single mediawiki instance that uses a single database so there is no option to pass it a database name to dump.
I can dump each individual databases and try to merge them. Has anybody tried that?
Dumping the dbs and trying to merge the databases will have duplicated keys everywhere. It could be done, but I don't suggest you to try going that way.
PS: It is fun that they were splitted for security and privacy and now search will be common, which voids those properties.
