[Mediawiki-l] Updating and moving at the same time; do the at the same time, or separately?

[Ken McDonald]

We'll be moving a 1.6.3 wiki to a new database. We also need to update 
to 1.9, as the new server runs only php 5. The documentation I've seen 
deals with either copying a wiki (unchanged) to a new server, or with 
upgrading in-place. Given our scenario, I'm wondering if it would be 
better to do both at the same time.

In particular, if I do a mysqldump of the old wiki, will that import OK 
into the 1.9 wiki? Or has the db table structure changed enough to 
prevent this? And if so, is there an easy way around it?

Copying images should be easy enough (I'm guessing here that the image 
data directory structure won't need to be changed in the new wiki), and 
likewise I think that transferring the mods to PHP files from old to new 
should be OK. Skins I'll worry about when we get to that point. Right 
now, I'm mostly concerned about getting the db transferred.

Also, is there anywhere that lists all of the new features that have 
been added from version to version? I know most projects have a 'version 
history' page, but I haven't stumbled across it in my Google searches yet...

Thanks,
Ken
