Stating in advance that I’m a totally beginner with the platform (but I managed as a syadmin a lot of web services over the last twenty years) I inherited a pretty old 4.5 installation of typo3, and would like to upgrade it to a supported release.
I would like to know which would be the best course of action to move between these two (pretty far) LTS versions: do I have to move to 6.x, then to 8.x and then to 10.x (following the relative upgrade documentation in each case)? and if I have to follow this road it’s ok to use the github tarballs of the latest 6 and 8 releases to do the intermediate upgrades?
are there any important gotchas that I’m missing?
thanks in advance for your assistance!
