I would like to know the best way to copy specific data from an Influx database from V1.8 to V2.2
As far as I can tell, the only way to get this data is to run a full database backup with influxd backup, then restore that database to a new server, then upgrade the server to 2.2 and then finally I can export a specific measurement in line protocol and restore it.
Is there perhaps an easier way I can export the data and import it? We have several TB of data in the database and I only need a subset of it.
Thanks in advance.
