Networking exists to move data around. You can easily spin up your agents on any platform under the sun. But storage is how The Big Cloud™ gets you. When you move your operations to a new storage platform like Tigris you have to migrate your data to its new home.

Tigris makes it easy with [bucket migration](https://www.tigrisdata.com/docs/migration/), but what if you want to move over everything all at once? The Tigris CLI has your back:

```
t3 migrate t3://world-domination-plans/agents/chatlogs
```

And your laptop will run the migration automatically, scanning over every object in your bucket and safely moving them over to Tigris. Here's how you set it up:

<!-- -->

## Bucket migration and you[​](#bucket-migration-and-you "Direct link to Bucket migration and you")

First, grab a Read-only keypair for your bucket in your old storage system. This will be the access key that Tigris uses to migrate your data. Use it in the `tigris bucket set-migration` command:

```
tigris buckets set-migration world-domination-plans \

  --bucket old-bucket-name \

  --endpoint https://old.provider.domain \

  --region region-such-as-yow \

  --access-key <access key id> \

  --secret-key <secret access key>
```

If you want the migration to be two-way (so new files added to your Tigris bucket get added to your old bucket just in case you don't want to continue your migration), make that keypair an Editor and pass the `--write-through` flag:

```
tigris buckets set-migration world-domination-plans \

  --bucket old-bucket-name \

  --endpoint https://old.provider.domain \

  --region region-such-as-yow \

  --access-key <access key id> \

  --secret-key <secret access key> \

  --write-through
```

Then you can run `tigris bucket migrate`:

```
tigris bucket migrate t3://world-domination-plans/
```

Kick back and relax! The Tigris CLI will keep on chugging until the job is done and all your data is safely on Tigris.

## Caveats[​](#caveats "Direct link to Caveats")

Keep in mind this has a few caveats. Namely that this migration isn't free. Running the `tigris bucket migrate` command issues a lot of `ListObjectsV2` and `HeadObjects` calls, which will cause you to incur Class A request costs according to [Tigris' pricing table](https://www.tigrisdata.com/pricing/).

This is also a very long-running operation, so if you run it on your laptop and go for a walk to the local cafejo, the migration will be suspended if your laptop is closed. Use something like a [vibe coding laptop wedge](https://makerworld.com/en/models/957883-the-wedge-and-the-wedge-xl?from=search#profileId-927154) to keep it running while you go touch grass. Worst case, spin up a small VPS / cloud server to run the command on.

If the migration does get interrupted, don't worry: the next time you run `tigris bucket migrate` it picks up where it left off instead of starting from scratch. No wasted work, no re-copying objects that already made it over.

## We'll keep innovating for your agents[​](#well-keep-innovating-for-your-agents "Direct link to We'll keep innovating for your agents")

At Tigris we believe that you(r agents) deserve a better experience with object storage. That's why we will keep innovating with [bucket migration](https://www.tigrisdata.com/docs/migration/), [forks/snapshots](https://www.tigrisdata.com/docs/snapshots-and-forks/), [bundles of objects](https://www.tigrisdata.com/docs/objects/bundle/), and more as we reinvent object storage based on how you wish it could work.

Ready to move your data home?

Zero-downtime migration from any S3-compatible provider. Tigris transfers your data lazily, with optional write-through syncing, so you migrate at your own pace without disrupting production.
