If you are using BioStar version 1.52 and above, you can use the following procedure to upgrade your BioStar version and reap the benefits such as bug fixes and new features.

If you have a BioStar version lower than 1.52 installed, you cannot upgrade to versions above 1.52 by simply deleting and installing the most recent BioStar. You will have to follow the procedure shown in the How to Resolve a Database Compatibility Issue to upgrade without any issues.

Upgrade Procedure

Deleting BioStar will not delete your database but please back up your database so that you may revert your database if the database upgrade fails.

1. To back up your database, see How to make a backup of MSSQL database.

2. Uninstall BioStar from the control panel.


3. Download the most recent version of BioStar installation file: Download link.
