Restore to New Host

I setup a new host so I can have a ‘staging’ environment. I re-created the same discourse installation with what should be the same version. I’m running version: 2.8.2.

First comment, as of version 2.8.2 my back up size has dropped from 282MB to around 90MB. Not sure why but I’m going to just with some intelligence added in that I’m taking advantage of.

I downloaded the latest archive from my forum, and uploaded to local storage on the new staging environment.

The restore fails due to:

This is your issue. Maybe use the same S3 bucket and use the same bucket? Maybe see that the hidden setting that’s called something like "download S3 in backup " is turned on. You’ll need to search or look on on the source for the setting name.

Or maybe you need to see that the rest of your uploads on the production site are on S3.

I have no S3 configured I’m guessing maybe the old server has some old data that didn’t get mapped to a valid S3 location.

I went back to the older server and I have 2 buckets configured, 1 for backups and 1 for media. I followed the guide and setup AWS S3 including the CDN.

When I run rake uploads:migrate_to_s3 which failed, I follwed that with a posts:rebake and that seems to have reduced the number of errors, but it still fails:

Please note that migrating to S3 is currently not reversible!

Is there a way to run migrate_to_s3 in a verbose mode to identify the post that’s the culprit?
