Timestamp lost after influx_inspect export -> influx write (migrating from 1 to 2)

InfluxDB 2
1

Hey everyone, good morning from Germany,

I’m currently trying to copy my time series from an Influx 1.8 to a new 2.4.0 instance. I seem to be missing something though.

I did the following:

  1. I exported my data from the 1.8 instance like this: influx_inspect export -database homeassistant -lponly -out ./homeassistant.lp
  2. I tried importing the data into the 2.4.0 instance like this: influx write --bucket homeassistant --file homeassistant.lp

Now it looks like every entry has the timestamp of the time of import, not the original timestamp. Is that correct? Is that expected behavior? That drives the time series useless because one dimension is lost.

What am I doing wrong?

Thank you
