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???)
also if a pro would give me an outline of how they would go about the test environment upgrade i would be very tyvm.
