Problem backup 1.8 restore 2.6

Hello dear Influx Community,

I have 2 InfluxDB instances on different machines (one Openhabian installatilon on CM4 and one docker instance) and having problems migrating the data.

Instance 1 (openhabian on raspberry4)

influx --version

How can i import the backup in my docker instance? Is it possible at all? What i am missing?

Thanks for any hints,

dont know why my former post was marked as spam by askimet and hided the post for 2 days :thinking:
anyway i bump this thread one time to be on top of the posts at least once…

i have solved it now. 3 days after me another user had a similar question: Import v1.x backup to v2.6 - #3 by FredAnna and the answer from user @Pooh pointed me to the right direction.

With Info from Upgrade from InfluxDB 1.x to 2.6 with Docker | InfluxDB OSS 2.6 Documentation i could upgrade my data from 1.x to 2.x

docker run -p 8086:8086 \
  -v influxdb:/var/lib/influxdb \
  -v influxdb2:/var/lib/influxdb2 \
