Hi @kcrazy - I am working on producing documentation to guide exactly this migration. Can you tell me about your dataset? How many shards, how much data (GBs), do you use flux or only influxql? The general recommendation is to export your data to line protocol using the Please let me know if you have more questions or what you encounter in your migration attempt. |

Hi, Thanks for your reply. My database size is around 100GB, but I’m not sure how many shards I have. I created a backup from InfluxDB v1.8 using the influxd backup command, and all backup files are stored in a folder. Can these v1.8 backup files be used to migrate the data to InfluxDB v3? I’ll also try the migration using your suggested method. Thanks again for your guidance. |

Let me answer the quick question now and I'll reply to your other questions soon.
You can execute the "show shards" influxql command on the 1.8 databases via the influx shell or the influxql query endpoint; but if you've already exported and not running influxdb anymore that isn't a path. But the number of shards isn't critical information; it's helpful to know a general size and scope of a database before doing a migration. |
