i am trying to transfer attachments from aws s3 to cloudflare r2, and i have transfered every file

like `https://whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com/original/2X/2/226249bf2000d559bcb6dee752497d1d23e4bb76.jpeg` to `https://discoursecdn.beginner.center/original/2X/2/226249bf2000d559bcb6dee752497d1d23e4bb76.jpeg`

then , i want to replace all url in my posts , from `whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com` to `discoursecdn.beginner.center`

i found someone have a try before in [How do I move my s3 upload bucket from one provider to another?](https://meta.discourse.org/t/how-do-i-move-my-s3-upload-bucket-from-one-provider-to-another/178484)

In this topic, i find how to replace string in all posts [Replace a string in all posts](https://meta.discourse.org/t/replace-a-string-in-all-posts/48729)

but when i run these command

```plaintext
rake 'posts:remap[whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com , discoursecdn.beginner.center]'

rake 'posts:remap["whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com" , "discoursecdn.beginner.center"]'

rake 'posts:remap["//whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com/" , "//discoursecdn.beginner.center/"]'

rake 'posts:remap[/whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com , /discoursecdn.beginner.center]'

rake posts:remap['whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com','discoursecdn.beginner.center']

rake posts:remap['//whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com/','//discoursecdn.beginner.center/']

rake posts:remap[whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com,discoursecdn.beginner.center]

rake posts:remap[whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com,discoursecdn.beginner.center]

rake posts:remap["whitewatercn-discourse.s3.dualstack.ap-northeast-1.amazonaws.com","discoursecdn.beginner.center"]

```

You can look at

```
Uploads.all.pluck(:url)

```

To see what’s there and copy paste that url
