Upgrade to 17.2 failed

Hello, we are trying to upgrade our test Appian server from 16.3 to 17.2. We have created the suite.ear.dodeploy file in /appian/ear folder but it results in a .failed.

I here attach the server.log and the suite.ear.failed. There are some "FATAL" and error... but we don't understand the cause.

09:35:59,709 INFO [stdout] (ServerService Thread Pool -- 84) 2017-06-06 09:35:59,708 [ServerService Thread Pool -- 84] FATAL com.appiancorp.common.web.StartupHaltingServletContextListener - Halting JVM startup: A fatal error occurred when importing system packages: Found 20 failures when importing. Will try again upon restart: /home/amognoni/appian/ear/suite.ear/web.war/WEB-INF/bundled-apps/system.zip

Any suggestions?

Thanks in advance!
