I changed the domain name for file storage (Tencent Cloud, compatible with S3). How can I update the old file link addresses in the posts to the new domain links? Thank you.

It’s almost certainly not 100% compatible. Is it compatible with Discourse? You’ve checked? Have a look at [Configure an S3 compatible object storage provider for uploads](https://meta.discourse.org/t/configure-an-s3-compatible-object-storage-provider-for-uploads/148916)
There’s a topic about using remap to switch buckets.
What I would do is set up a new server with teh new S3 config, set the `SiteSettings.include_s3_uploads_in_backups` to true and see if it’ll restore.

I believe it is 100% compatible because after configuration, I used it without any problems, including uploads and backups, which are completely consistent with Amazon AWS.

There used to be a topic about how to use `remap` to switch to a different bucket. I don’t see it.
The way that I would recommend would be to switch servers as described above. Doing it once you have multiple buckets in `Uploads` is much more difficult.
