2.4.0 is still in alpha, update your sites at your own risk. I would recommend updating your sites locally (not directly on production but on your server, testing for any kinks then updating the production site)

To update your 2.3 site you will just need to replace the sapphire/ cms/ and jsparty/ folders with the new ones from 2.4 alpha (or if you are using svn then remove jsparty althogether!).

Note your existing modules *could* break. Some major and minor API changes in 2.4 so you will need to check they do not break. We'll provide a full guide and changelog to upgrading when 2.4 is nearer stable release.

Upgrade notes regarding changes in classes, etc. are at http://doc.silverstripe.org/doku.php?id=upgrading:2.4.0

Will, it'd be nice if the upgrading file and the above page had more explicit instructions as you mention - i.e. copy/remove x folders. The upgrading file with the 2.4 download is out of date.

I received an error when upgrading... http://open.silverstripe.org/ticket/5059

Cheers

Not trying to be confrontational but would say it should be kept up-to-date, if not necessarily detailed and complete, to help downloaders of early releases like myself who end up posting to forums because the info's missing.

Re: my issue - I ended up deleting the cache folder and that resolved my issue and dev/build on 2.4 ran fine As to how people can locate their own cache folder I don't know.

Are there instructions published yet about how to begin using the hierarchical URL/page structure after upgrading to 2.4? All I've seen is a quick mention of it being a mode to choose between flat URLs and hierarchical ones.
