We are running an old version of Mattermost on Cloudron (7.10.3) and find that the process to upgrade is well and far beyond what we are capable of technically.
We are hoping that we can run the process outlined here:
https://docs.mattermost.com/manage/bulk-export-tool.html
To export and import a json file from the old server to the new one.
None of the paths in the above procedure lien up however so we are confused as to how we can even get a file off that Cloudron instance?
Any help appreciated.
