It is always recommended to stay up to date with the latest version of any of software to avoid running into unnecessary bugs by receiving the latest updates from us. Three things to remember everytime you run an upgrade: Backup, backup, and backup.
Make it a habit to run a backup before uninstalling ANY component; this includes Komento. There are many school of thoughts or ways to backup your site, but please stick with what you're comfortable with. We would like to recommend you to read through this documentation on Backing Up Your Site.
Upgrading from older version of Komento to a newer version is really simple. There are two options that you can go with.
- Install the latest installer over the existing component.
- OR, uninstall the previous version and install the latest version again.
To obtain the latest version of Komento, all you need to do here is to access to your Dashboard area and download the latest version of Komento.
After you have acquire the installer package, proceed to your Joomla Extension Manager and browse for the downloaded file and hit the upload and install button. You may follow these documentation as a guide.
Rest assure that the process of uninstalling Komento will not remove the existing comments and it will remain intact. The only changes / removals during the upgrade is the files. If you've made any customization, be sure to back it up first before runs the upgrade process.
