Downgrade InfluxDB from 2.x to 1.8


we upgraded InfluxDB from 1.8 to 2.x version. A few weeks later we are seeing strange behavior and services that are writing to DB sometimes just stop writing and everything is hanging until InfluxDB is manually restarted. After restarting everything starts working and after some period it stops again. We can’t figure out what is the issue. The only thing that we know is that we didn’t have this issue with the 1.8 version. How can we downgrade to the 1.8 version so that we don’t lose data that was ingested in 2.x version? What is the safe downgrade path? Thanks

Hello @DCRL,
I don’t know if there is an official downgrade path.
How much data have you written?
I think I might suggest using a client library to query and write the data to a 1.x instance.


we have 5,5TB of data in 2.x version.
Can you explain a little bit more about “using a client library to query and write the data to a 1.x instance”? Thanks

How come there is no official downgrade path? This is something that is pretty much normal in database upgrades.
