In the process of migrating an established site to a new server. I used my SaaS versioning system (Beanstalk) to push the files to the new server. I seem to have run into a problem with ownership of directories and files, and permission levels for certain directories and files. I have shell access to my server and can recursively chmod/chown the directories and files. I'm looking for documentation on which dirs/files need to be owned by the server (or user nobody) and which dirs/files need special permissions. Version 2.4. Thank you for any help you can provide.

Sorry for the late reply. Basically the only files that need writing permissions are:

assets/
the whole directory, all files

mysite/_config.php
only while using the default SilverStripe install routine, unless all database data have allready been entered.

silverstripe-cache/
Only if it exists. If it doesn't, Silverstripe will use the default tmp directory for its cache files
