Migrate data to InfluxDB Cloud Serverless powered by the v3 storage engine from other InfluxDB instances powered by TSM including InfluxDB OSS 1.x, 2.x, InfluxDB Enterprise, and InfluxDB Cloud (TSM).
There are important things to consider with migrating to InfluxDB Cloud Serverless. The following questions will help guide your decision to migrate.
Yes, you should migrate. Series cardinality is a major limiting factor with the InfluxDB TSM storage engine. The more unique series in your data, the less performant your database. The InfluxDB 3 storage engine supports near limitless series cardinality and is, without question, the better solution for high series cardinality workloads.
Yes, you should migrate. InfluxDB Cloud Serverless lets you query your time series data with SQL. For more information about querying your data with SQL, see:
<!-- #### Do you want better InfluxQL performance? **Yes, you should migrate**. One of the primary goals when designing the InfluxDB v3 storage engine was to enable performant implementations of both SQL and InfluxQL. When compared to querying InfluxDB powered by TSM (InfluxDB OSS 1.x, 2.x, and Enterprise), InfluxQL queries are more performant when querying InfluxDB powered by the v3 storage engine. -->You should maybe migrate. InfluxDB Cloud Serverless instances are available from the following providers:
{{< cloud_regions type=iox-list >}}
If your deployment requires other cloud providers or regions, you may need to wait until the InfluxDB 3 storage engine is available in a region that meets your requirements. We are currently working to make InfluxDB 3 available on more providers and in more regions around the world.
You should maybe migrate. Flux queries are less performant against the InfluxDB 3 storage engine. Flux is optimized to work with the TSM storage engine, but these optimizations do not apply to the on-disk structure of InfluxDB 3.
Before you migrate from InfluxDB 1.x or 2.x to {{< product-name >}}, there are schema design practices supported by the TSM storage engine that are not supported in the InfluxDB 3 storage engine. Specifically, InfluxDB 3 enforces the following schema restrictions:
For more information, see Schema restrictions.
If your schema does not adhere to these restrictions, you must update your schema before migrating to {{< product-name >}}.
