Slack to MM migration: Unable to upload file. File is too large

Troubleshooting
1

Hello. I’m trying to migrate from Slack to MM. I’ve already done all the steps and now I need to upload the content to my MM server.

When I run the command:

mmctl import upload ./mattermost-bulk-import.zip

I get this error:

WARNING: server version 9.8.1.9253470812.4xxxxxxxxxxxxxxxxxxxxxxxe459.false doesn’t match mmctl version 8.0.0

Error: failed to create upload session: : Unable to upload file. File is too large.

I’ve already updated the: MM_FILESETTINGS_MAXFILESIZE to: 75161927680 (which should be 70GB). My .zip weighs 36GB.

My server runs through Traefik. I’m unsure if I need to add any other variables…

MM_SQLSETTINGS_DRIVERNAME=postgres
MM_SQLSETTINGS_DATASOURCE=postgres://postgres:xxxxxxxxxxxxxxxxxx@$(PROJECT_NAME)_mattermost-db:5432/$(PROJECT_NAME)?sslmode=disable
DOMAIN=https://$(PRIMARY_DOMAIN)
MM_PLUGINSETTINGS_ENABLE=true
MM_PLUGINSETTINGS_ENABLEUPLOADS=true
MM_FILESETTINGS_MAXFILESIZE=75161927680

Team Edition
Mattermost Version: 9.8.1
Database Schema Version: 120
Build Number: 9253470812
Database: postgres

I appreciate the help.
Thanks.

In case the version mismatch has anything to do with this, you can grab the right version of mmctl via https://releases.mattermost.com/mmctl/v9.8.1/linux_amd64.tar
