  Upgrading your AuthAnvil Two Factor Auth installation from v4.0 to v4.1 (Legacy)
  Simply follow the steps below to make sure your authentication server is properly upgraded to the latest version of AuthAnvil.
  Step 1 Backup your existing data by creating a backup (bup) file.
  Open a command window and navigate to the C:Program FilesScorpion SoftwareAuthAnvilAuthAnvilTools directory.
  Confirm that your file is valid by ensuring that it is well-formed XML. Move it to a secure location for later restoration.
  Step 2 Upgrade AuthAnvil Strong Authentication Server
  Download the AuthAnvil 4.0 to 4.1 update kit from here.
  Unzip it and run the UpgradeAuthAnvil.bat file inside the folder. NOTE: Make sure to run this batch file from an elevated command prompt.
  The updater will go through, back up your existing files, then deploy the new ones.
  Once the upgrade has completed successfully and has been tested, you can remove the backup files.
  NOTE: This method supports upgrades from AuthAnvil 4.0 to 4.1 only. For instructions on upgrading from AuthAnvil 3.5 or earlier, please refer to the appropriate upgrade guide. The AuthAnvil 4 installer will deploy the AuthAnvil 4.1 files for all new installs and upgrades.
  Step 3 Test upgraded AuthAnvil install
  With all the previous configuration settings now restored, your installation SHOULD be back and fully working.
  To test that this is true for AuthAnvil, follow these steps:
  Using an AuthAnvil account that is a site admin, log in to the AuthAnvil Manager using your AuthAnvil credential. The AnvilManager should display the version 4.1.0.15.
  Click the Users tab, click a user name, then click Token Information and then Test Token. Follow the on screen instructions and ensure you can successfully authenticate that token.
  Once AuthAnvil is fully tested to be working, you can turn to upgrade all your AuthAnvil agents.
  NOTE: If you are running Kaseya or another RMM tool to manage AuthAnvil agents, you may need to update the MSI kit used for deployment. This file is available on the Customer Portal under Tools.
  Step 4 Backup your new AuthAnvil configuration and settings
  To run the backup, run the command aabackup.exe followed by the SQL instance name.i.e. aabackup.exe SBS2008AUTHANVIL
  Using a tasked schedule, you can configure it to routinely backup the data and make it available to your normal server backup sets. We have a tool available to help you do that. For more information, check out this blog post.
