If you are upgrading BioStar 2 you can install the new version on top of the old version without deleting the old version.
However, you cannot upgrade from a very old version such as 2.0 to 2.4 in one upgrade because that process is unsupported.
Please refer to this article to upgrade sequentially.
- When you delete BioStar 2, it will delete the MariaDB database as well.
BioStar 2's database has gone through a few changes since it's release.
The AC database started out with the SQLite Database and in version 2.2.1, the MariaDB T&A database was released.
Starting version 2.3, both databases became Maria DB by default (express installation). Hence the backup method has changed as well.
Refer to the image below to see the changes in the Database in BioStar 2 versions.
If you are using any DB Link program with the SQLite database in BioStar 2.2.1 or below, you will have to make changes in the software to make it compatible with Maria DB.
Back Up the Database
Always back up your database before deleting or upgrading BioStar 2.
You can find instructions in the following link: How to Back Up and Restore the Database
You will have to follow the upgrade path below to upgrade to the most recent version successfully.
Do not uninstall the current version and install the next version.
You can simply install the next version on top of the current version and it will migrate the database.

** Warning: Do not upgrade your Xpass firmware to 2.4.0 (2.4.1 and above are fine). Your device will malfunction.
32 bit to 64 bit upgrade
If you're attempting to upgrade from a 32 bit BioStar 2 to 64 bit BioStar 2, you will see the error below:
