You may find this useful:

Not really.

There was a problem with search in 1.6 involving an inability to
search for small or common words. I'm not sure if that is your
problem, but it is fixable without upgrading, by changing the MySQL
configuration. Upgrading MediaWiki would also fix it.

I would think that patching the XSS vulnerabilities would be fairly
important. File deletion in 1.6 was irreversible, so an XSS attack
could lead to all your images being permanently deleted. I'm sure you
keep regular backups, but still, I would think that it would be a bit
of a nuisance.

Upgrading to 1.16 will allow you to use PHP 5.3, which is now the only
supported branch of PHP. Running an old version of PHP means that you
are exposed to the dangling pointer issues which are steadily
discovered in it. Memory corruption bugs in PHP are not fully
researched for potential security implications. At least, not in public.

Also there are a couple of hundred extensions which have been written
since you last upgraded, almost none of them support 1.6.10. Maybe you
can find something compelling in there. Maybe even something to do
