# Upgrading Smart AMS

You can upgrade the software from Smart AMS v. 1.2, Smart AMS v. 1.3, Smart AMS v. 1.4, or Smart AMS v. 1.5 to Smart AMS v. 1.6. If an older version of Smart AMS than v. 1.2 is already installed, please uninstall it before installing Smart AMS v. 1.6.

If you have a custom-designed version of Smart AMS v. 1.2 installed on the machine, please uninstall it before installing the standard version.

Any older versions of Erlang OTP or RabbitMQ Server, detected on the machine during the upgrade, will be preserved.

After the upgrade has completed, you can import your .xlsx configuration file of a previous Smart AMS version into Smart AMS Config v. 1.6. The configuration parameters introduced in Smart AMS v. 1.6, which were not available in the old version, will be set to their default values.
