&lt;p&gt;After migrating sys db and running the application we get the following error :&lt;/p&gt;
&lt;pre&gt;&lt;code&gt;    Caused by: ch.ivyteam.ivy.persistence.PersistencyException: Unknown system property 'Database.Id'
    at ch.ivyteam.ivy.application.internal.ApplicationConfigurationManager.lambda$32(ApplicationConfigurationManager.java:1351)
    at java.util.Optional.orElseThrow(Optional.java:290)
    at ch.ivyteam.ivy.application.internal.ApplicationConfigurationManager.getSystemProp(ApplicationConfigurationManager.java:1351)
    at ch.ivyteam.ivy.application.internal.ApplicationConfigurationManager.getSystemProperty(ApplicationConfigurationManager.java:1336)
    at ch.xpertline.xent.oauth.ivy.IvySecure.getIvySalt(IvySecure.java:17)
&lt;/code&gt;&lt;/pre&gt;
&lt;p&gt;Any idea what is missing ?&lt;/p&gt;
&lt;p&gt;Best regards

You never saw it on a configuration UI. It is an identifier for the database and so it makes no sense in a yaml file, that is why we do not convert it.&lt;/p&gt;
&lt;p&gt;Please use another way to get a constant Number (e.g. In a File or own Database)&lt;/p&gt;</description><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">Christian Strebel</dc:creator><pubDate>Tue, 01 Oct 2019 02:57:22 -0400</pubDate><guid>https://answers.axonivy.com/questions/4017/ivy-7-2-1-7-3-1-migration/4035</guid></item><item><title>Answer by nndiem</title><link>https://answers.axonivy.com/questions/4017/ivy-7-2-1-7-3-1-migration/4028</link><description>&lt;p&gt;I already set autoconvert is true, why do I need add DatabaseId manual to ivy.yaml?. I think It should auto migrate all system property from database to ivy.yaml. &lt;/p&gt;
&lt;p&gt;In the meantime, I try to add it manually to ivy.yaml like this in the root level. &lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;Database.Id: -4615454054944818312&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;I still use the old method &lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;ApplicationConfigurationManager appConfigManager = (ApplicationConfigurationManager)                   &lt;br&gt;
        ApplicationConfigurationManagerNavigationUtil.getApplicationConfigurationManager(Ivy.wf().getApplication());
    return appConfigManager.getSystemProperty("Database.Id").getLongValue();&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;But It does not work. Do you have any idea?&lt;/p&gt;
&lt;p&gt;Thanks&lt;/p&gt;</description><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">nndiem</dc:creator><pubDate>Thu, 26 Sep 2019 00:46:57 -0400</pubDate><guid>https://answers.axonivy.com/questions/4017/ivy-7-2-1-7-3-1-migration/4028</guid></item></channel></rss>
