Hi @it33, I guess it might be the "Current working directory" and the FileSettings.Directory property defined in config.json didn't work together properly, here is what I thought was happend:
The step 6 in upgrade doc said
- Run
./platform -upgrade_db_30...
which implied that the current directory is {mattermost}/bin/,
and in the official config.json, the FileSettings.Directory is set to "./data/" by default,
then the data path became {mattermost}/bin/data which doesn't exist of course.
Maybe if we ran bin/platform -upgrade_db_30 under {mattermost} while upgrading, then the problem won't happen.
Below is the logs produced during upgrading:
