Hello. Wow. No, unfortunately I cannot confirm that you can upgrade from 2.0 
to 2.2 without headaches. :-)

Please *triple-check* that you have a full backup of your current working 
installation. There are indeed a huge number of changes since 2.0.13 released 
in 2005 (151 versions have been released).

Then you should be able to install the new version, try to read through the 
ReleaseNotes and the documentation in order to fix everything that is broken. 
If it doesn't seem fixable, you can restore your previous setup from the 

The most important changes are outlined in the ReleaseNotes, in the sections 
about Version 2.1.0 and Version 2.2.0.

I suspect that the wiki pages will work mostly fine and you'll be able to 
recover all your content, but that a number of configuration variables and 
options have changed in the meantime and the wiki could look weird, broken or 
even not function at all. Also some recipes could fail to work any more, but 
there could be a more recent version in the cookbook.

Or, there may be a better idea. You could also try to upgrade in a number of 
steps, taking your time :
1. upgrade to 2.1.0 (with everything fixed and working), 
2. upgrade to 2.1.27 (idem) last 2.1 stable 
3. upgrade to 2.2.0  (idem) first 2.2 stable
4. upgrade to 2.2.16 (idem)

and every time reading the release notes :

PmWiki has more features now -- not sure if it is all good -- and more recipes 
(plugins, modules). 

Good luck,
