Description

Hello! We are considering moving from slack to rocketchat, but we are faced with the problem of migration. The problem is that the full export from our slack is 54GB (includes emails and attachments). When trying to import, rocketchat throws an error.

The documentation states that the recommended export file size is 15Mb. What is the maximum size of the export file?

Hi! Sorry for the late response here.
Missed it some how :frowning:

Were you able to solve this?

We are interested in improving this import as this is always a hot topic within our community, but we can only improve with the direct help from users importing their backups.

Over the years we have found a variety of exports that end up not being imported.

Please, feel free to contact me at community@rocket.chat so we can help you further :slight_smile:

Thanks!
