Steps to Migrate from influxdb 1.7.11 to influxdb 1.8.10

Hi. I know it seems a old request but we are also working to use Influxdb 2.7.1 but our prod environmet today is still using the version 1.7.11.
We would like to know what we need to considerer in order to migrate from 1.7.11 to 1.8.10.
Those are our configuration.

INFLUXDB_UDP_ENABLED true
INFLUXDB_DATA_INDEX_VERSION tsi1
INFLUXDB_DATA_CACHE_MAX_MEMORY_SIZE 20g
INFLUXDB_COORDINATOR_WRITE_TIMEOUT 30s
INFLUXDB_COORDINATOR_QUERY_TIMEOUT 360s
INFLUXD_STORAGE_WAL_MAX_WRITE_DELAY 15m
INFLUXD_HTTP_READ_HEADER_TIMEOUT 30s

Hello @Alemar,
In all honestly if you can hold off migration until 3.x is out, I recommend that.
There are several features in 2.x that aren’t part of the product plan currently for 3.x. Most notably that you’d have to learn Flux for 2.x. 3.x supports InfluxQL and SQL so you wouldn’t have to convert your queries 2x.
Also 3.x is showing crazy performance enhancements and is a complete rewrite of the storage engine.

Is this something you can hold off on?

Our plan is to go first to 1.8.11 and then all new implementation to go to new version. In this case could be Flux 3. Now We need to go to 1.8.11 to have the benefits of this version since 1.7 give us some performance issues.
