InfluxDB Founder & CTO here. We worked hard to support InfluxQL in 3.x and it supports the v1 write API. Admittedly, it will be a migration to move and we haven't yet built the tooling, but we felt it was important to get the 3.0 release out even though we don't have the migration tooling built yet. Our plan is to have that available later this year.

The 2.x to 3.x move is, admittedly, much harder. This is because of the language Flux. We haven't been able to bring that over to 3.x in a way that makes it useful. We actually built a bridge for it in our cloud offering, but our experience is that the performance isn't good enough to be acceptable for customers wanting to upgrade. If they want to make the move, adopting SQL or InfluxQL is likely the only path.

We'll continue to develop 3.x and we'll build more migration tooling over time. I think we can build specialized tooling to help Flux users migrate over to 3.x with query translation tools, but there are more features we need to land in 3.x to enable that first.

We're committed to the technology stack (Apache Arrow & DataFusion) and the 3.x line. We have no plans for another major release. I'll be happy if we end up releasing 3.56.2 8 years from now.
