The same issue at upgrading 5.3.3 to 5.4.0. I use PostgreSQL.

@mzch Thanks for your feedback. Please let me know:

1. How 5.3.3 is started? If via docker, please let me know detailed docker command line you are using
2. What command you are using to perform the upgrade

1. Yes, 5.3.3 ran successfully. I don't use docker.
2. I did as below:

• bin/upgrade.sh .
• bin/server.sh start

Finally I created backup file using bin/backup-db.sh ../backupfile, dropped database and re-created it, and restore data from backupfile. Now I run 5.4.0 successfully.

@mzch the command used to upgrade seems incorrect. The procedure should be:

1. Extract onedev-5.4.0.zip to a folder say "/path/to/onedev-5.4.0"
2. Open terminal and run command:

$ /path/to/onedev-5.4.0/bin/upgrade.sh /path/to/onedev-5.3.3

3. After running above command, "/path/to/onedev-5.3.3" will be upgraded to 5.4 (to avoid confusion, it is suggested to name onedev directory without version info)

Oh, thanks. I was wrong about upgrade process. I'd like you to update Upgrade Guide to have a more clear understanding...

Thanks for the suggestion. Will do that.
