How to in place upgrade App Volumes 2.12 to 2.12.1

Yes! App Volumes 2.12.1 was just released and it allows Upgrades!

What’s New in This Release

The latest release of App Volumes includes an improved upgrade process, Writable Volumes exclusions, and important security fixes.

Improved Upgrade Process
You can now upgrade from App Volumes 2.12 to App Volumes 2.12.1 without uninstalling your existing 2.12 installation. Upgrading from versions earlier than 2.12 still requires App Volumes Manager and agent binaries to be uninstalled before proceeding with 2.12.1 installation.
Note – As a best practice with any system change, ensure that you have a backup of your systems including security cerificates and configuration files before performing an upgrade. Customizations to App Volumes outside the normal configuration interface may not be retained.
Writable Volumes Exclusions
An App Volumes administrator can exclude specific file paths or registry keys from being overwritten, thus excluding them from being persisted across sessions.

Miscellaneous Updates

Nginx configuration file has been upgraded.
You can now use non-ASCII characters when naming the datastore in App Volumes Manager.
The App Volumes Manager remembers and displays the last selected domain.
The Pending Activities tab in App Volumes Manager displays the background jobs that are in progress in App Volumes.
