Just conscious that this is a big upgrade, but I couldn't actually see anything specific in the docs about v1→v2 being a major issue, and nothing listed in the breaking changes link. But then there are no issues listed there for v2 at all, in fact nothing since 1.137. So hopefully this is good news and I can just go ahead, with the usual caveats around backing up the database, etc. Just wanted to get some reassurance :).
