I have old data files from a v1 InfluxDB, how do I convert them in something ingest-able by a v2 instance?

Weird issue here: last month I tried to upgrade my v2 InfluxDB instance, but for some reason I failed and went back to v1.11, so it started to write data in a different location and I “lost” the V2 data. Now I fixed the upgrade and I’m back to v2.8.11, it reads/writes the data in the previous location, but I have one month of data in V1 format that I need to convert in something I can import in the V2 instance.
This is not a backup, these are raw files used by InfluxDB with directories such as wall, data, meta.

Is there some way to load this data in a V1 Influx on some server, then make a backup that can be loaded in the V2 instance?

Thanks.

Hello @bfontaine,
Welcome!
Here are the upgrade and migrate guides for 1.x->2.x

Let me know if that helps :slight_smile:
