Upgrade error 413

[giant]

I'm having problem upgrading EspoCRM from 5.0.5 to 5.1.2 because I'm getting 413 error.

I know this is related to Apache and LimitRequestBody setting, but

Is it possible to upload the upgrade file to the server via (s)ftp and then somehow trigger the process to start and therefore avoid using the standard upload form?

Ok maybe reading documentation would help, alternative way is running cli

php upgrade.php /path/to/upgrade/package.zip
