Access files uploaded to Parse.com after Heroku migration

Question

I am attempting to migrate my server from Parse.com over to Heroku with their one click migration. Their documentation says that Parse Server supports "file" type, but I can't find any documentation on transferring these files so Heroku can access them.

Answer 1

This isn't an answer but I've been having the same issue/dilemma and have partial information that might be helpful in eventually finding an answer. I did a migration and took a look at some of the stuff going on.

Example, photoObj.get('file').url();

On Parse Hosting: files point to the following: http://files.parsetfss.com/parseFileKey/fileName.ext

This is stored on some amazon S3 thing. Basically this points to: https://s3.amazonaws.com/files.parsetfss.com/parseFileKey/fileName.ext

After migrating to Heroku/MongoLab, photoObj.get('file').url() points to the following: http://files.parsetfss.com/newHostFileKey/fileName.ext

newHostFileKey is something we designate in the parse-server setup and seems to be automatically generated via this setting.

I don't see any evidence so far that the migration tool moves files from Parse Hosting to the new host/db.

File uploading to the new host works fine. On the new host, if one generates a new file it ends up pointing to something like this: http://newHostURL/parse/files/appID/fileName.ext

parse is whatever you designate at the startup of your parse-server like app.use('/parse', api);

appID is whatever you designate at the startup of your parse-server like

var api = new ParseServer({ appId: 'appID', fileKey: 'newHostFileKey' });

Changing the url point of an Parse Hosted file to fit the new host pattern doesn't yield anything (file not found) etc.

I have no idea how new files are being stored and to where the url routes to.

With new files that are uploaded via the new host, I notice that some new tables/collections are created in the MongoLab DB. These are fs.chunks and fs.files

fs.chunks is where the data of the file is being stored (I think). So under the new heroku/mongolab setup, files seem to reside "in" the DB.

As for what the best way is to migrate images from Parse hosting to new hosting is, I have no idea but I'm not sure there is a straightforward answer that is publicly out there at this point.
