Anyone have an opinion here or any formal prior art for us to build on? >
Maybe this question should be more phrased as to which upgrade paths each individual has time in helping and fixing users out? If you are voting for official support for the 3.0 upgrade path then that should imply you are putting up your hand in helping provide that official support in the community. (Whatever officially supported is deemed to be) I am only for supporting upgrades from latest 3.11. It makes life a lot simpler for all of us, and helps focus our community time on CEPs and otherwise maintaining our supported branches. At The Last Pickle we have always recommended avoiding 3.0, including upgrading from 2.2 directly to 3.11. We (now DataStax) will continue to recommend that folk upgrade to the latest 3.11 before upgrading to 4.0. regards, Mick
