advice about upgrading a complicated site
21 February 2011 at 12:14pm
Hi, so I have been going through the process of analyzing the difficulty of upgrading a site to a new version. I have found it very difficult identifying what versions of some modules are installed and also finding suitable documentation on some of the modules outlining what version of the core they are compatible with. any experienced advice would be much appreciated:
core 2.3.3 -> not sure (is it best to go to the latest? i couldn't tell if all my modules would work with 2.4???)
blog
cmsworkflow
dataobjectmanager
genericdataadmin
subsites
subsite_blogalso if a pro would give me an outline of how they would go about the test environment upgrade i would be very tyvm.

I have found it very difficult identifying what versions of some modules are installed and also finding suitable documentation on some of the modules outlining what version of the core they are compatible with.
This information should be on their module listing page. Module authors can select supported versions for what version. If you follow the discussion on the core dev mailing list you would have heard of the new module manager which is coming in SS3.0. It will fix this exact issue (but is a while off)
core 2.3.3 -> not sure (is it best to go to the latest? i couldn't tell if all my modules would work with 2.4???)
Upgrading to 2.3.* will definitely be easier then 2.4 but you may need to upgrade later on.
My best advice is to download a copy of the site to your local computer, upgrade each of those modules to their latest versions, upgrade your site code with the instructions http://doc.silverstripe.org/sapphire/en/changelogs/2.4.0#upgrading.
It won't work 'out of the box' unless it's your lucky day but see what errors you get, most of the time they are easy fixes.

Hi Will, thanks for the prompt response. I could have made my post clearer cause I want to upgrade From 2.3.3 not to it. Anyway, I am following your advice and am at a stage where I am setting up my testing environment for upgrade. the site developer has used svn to manage all the modules used on the site and also the site files themselves (mysite, themes, etc). I noticed one of the modules was using a branch. should I continue using the branches or use the trunk?
thanks for the help,
Dan
