[keycloak-user] Still getting index error when upgrading to 1.3.1.Final

I did a fresh install with mongodb 3.0 and everything worked fine running 1.3.1.Final. However, I need to upgrade from 1.2.0.Beta1 so I tried the same configuration with everything except this time migrating the old database data. I get the following error: at java.lang.reflect.Constructor.newInstance(Constructor.java:422) at org.jboss.resteasy.core.ConstructorInjectorImpl.construct(ConstructorInjectorImpl.java:148) ... 19 more Caused by: java.lang.RuntimeException: Failed to update database at org.keycloak.connections.mongo.updater.impl.DefaultMongoUpdaterProvider.update(DefaultMongoUpdaterProvider.java:90) at org.keycloak.connections.mongo.DefaultMongoConnectionFactoryProvider.lazyInit(DefaultMongoConnectionFactoryProvider.java:99) ... 36 more Caused by: com.mongodb.CommandFailureException: { "serverUsed" : "kcdb/ 172.17.0.69:27017" , "nIndexesWas" : 1 , "ok" : 0.0 , "errmsg" : "index not found with name [realmId_1_name_1]"} at com.mongodb.CommandResult.getException(CommandResult.java:71) at com.mongodb.CommandResult.throwOnError(CommandResult.java:110) at com.mongodb.DBCollection.dropIndexes(DBCollection.java:847) at com.mongodb.DBCollection.dropIndex(DBCollection.java:1349) at org.keycloak.connections.mongo.updater.impl.updates.Update1_2_0_CR1.convertApplicationsToClients(Update1_2_0_CR1.java:33) at org.keycloak.connections.mongo.updater.impl.updates.Update1_2_0_CR1.update(Update1_2_0_CR1.java:23) at org.keycloak.connections.mongo.updater.impl.DefaultMongoUpdaterProvider.update(DefaultMongoUpdaterProvider.java:79) ... 37 more 01:17:00,691 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([("deployment" => "keycloak-server. I mentioned this before and Stian was going to look into it; at the time he thought it might be due to using mongodb 3.0. However, mongodb 3.0 works fine with a fresh install.
