# Migrate data to InfluxDB Cloud Dedicated

Migrate data to InfluxDB Cloud Dedicated from other InfluxDB instances powered by TSM including InfluxDB OSS 1.x, 2.x, InfluxDB Enterprise, and InfluxDB Cloud (TSM).

## Should you migrate?

There are important things to consider with migrating to InfluxDB Cloud Dedicated. The following questions will help guide your decision to migrate.

#### Are you currently limited by series cardinality?

**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 limitless series cardinality and is, without question, the better solution for high series cardinality workloads.

#### Do you want to use SQL to query your data?

**Yes, you should migrate**. InfluxDB Cloud Dedicated lets you query your time series data with SQL. For more information about querying your data with SQL, see:

-   [Query data with SQL](/influxdb3/cloud-dedicated/query-data/sql/)
-   [InfluxDB SQL reference](/influxdb3/cloud-dedicated/reference/sql/)

#### 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.

#### Do you depend on a specific cloud provider or region?

**You should maybe migrate**. InfluxDB Cloud Dedicated instances are available from the following providers:

-   **Amazon Web Services (AWS)**
    -   US East (Virginia)
    -   EU Frankfurt

If your deployment requires other cloud providers or regions, you may need to wait until the v3 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.

#### Are you reliant on Flux queries and Flux tasks?

**You should not migrate**. InfluxDB Cloud Dedicated doesn’t support Flux.

## Before you migrate

Before you migrate from InfluxDB 1.x or 2.x to InfluxDB Cloud Dedicated, 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:

-   You can’t use duplicate names for tags and fields.
-   By default, measurements can contain up to 250 columns where each column represents time, a field, or a tag.

*For more information, see [Schema restrictions](/influxdb3/cloud-serverless/write-data/best-practices/schema-design/#schema-restrictions).*

If your schema does not adhere to these restrictions, you must update your schema before migrating to InfluxDB Cloud Dedicated.

## Data migration guides

### [Migrate data from InfluxDB Cloud to InfluxDB Cloud Dedicated](/influxdb3/cloud-dedicated/guides/migrate-data/migrate-tsm-to-cloud-dedicated/)

To migrate data from TSM-powered InfluxDB Cloud to InfluxDB Cloud Dedicated powered by the v3 storage engine, query the data in time-based batches and write the queried data to an InfluxDB 3 database in your InfluxDB Cloud Dedicated cluster.

### [Migrate data from InfluxDB 1.x to InfluxDB Cloud Dedicated](/influxdb3/cloud-dedicated/guides/migrate-data/migrate-1x-to-cloud-dedicated/)

To migrate data from a TSM-powered InfluxDB 1.x (OSS or Enterprise) to an InfluxDB Cloud Dedicated cluster, export the data as line protocol and write the exported data to your InfluxDB Cloud Dedicated database.
