Yes, this is not a problem. Upgrade instructions can be found on page 165 and beyond of our online documentation: http://www.lansweeper.com/documentation.pdf
We do recommend performing a database backup prior to upgrading, just to be safe. To take a backup of your database:
• Create a copy of Program Files (x86)\Lansweeper\SQLData\lansweeperdb.sdf, if you are using SQL Compact as your database server.
• Right-click on the lansweeperdb database in SQL Server Management Studio and select Tasks\Back Up, if you are using SQL Server as your database server. If SQL Server Management Studio isn’t installed on your Lansweeper server, we recommend downloading it online. (You will need to perform a search for the Management Studio that’s compatible with your particular edition and version of SQL Server.)
