My upgrade failed.
- On-Premise Server + WebMail Installations: Version 6.0 > Current Version 6
- Webmail Only Installations: Version 6.0 > Current Version 6
If you run into any troubles with the upgrade you may need to re-run the upgrade process.
Assuming that your last version was 6.20.1; Login to your Atmail database and execute the following command.
mysql> update Config set keyValue = "6.20.1" where keyName = "version";
This will fool the WebAdmin update scripts and enable re-running the sql schema updates via the WebAdmin > License > Update Software.
Following the success of the WebAdmin update, please then execute the server-update.php file as the update page will instruct you.
php server-update.php 6.20.1
