Hi, we have a client using key cloak 3.4.3 and now wants to update to latest and greatest key cloak. We initially started migrating h2 database as we have it on one of client’s machine and then eventually will do with oracle in test and prod env. we tried with installing new keycloak 8 version on clients local machine and copied data folder from older keycloak 3.4.3 instance and it does not worked. further we tried with upgrading from keycloak 3.4.3 to keycloak 6 and it worked but any further upgradation fails with error as “Caused by: java.lang.NullPointerException at org.keycloak.migration.migrators.MigrateTo8\_0\_0.migrateRealmCommon(MigrateTo8\_0\_0.java:72) at org.keycloak.migration.migrators.MigrateTo8\_0\_0.lambda$migrate$0(MigrateTo8\_0\_0.java:49) at java.util.LinkedList$LLSpliterator.forEachRemaining(LinkedList.java:1235) at java.util.stream.ReferencePipeline$Head.forEach(ReferencePipeline.java:647) at org.keycloak.migration.migrators.MigrateTo8\_0\_0.migrate(MigrateTo8\_0\_0.java:49) at org.keycloak.migration.MigrationModelManager.migrate(MigrationModelManager.java:105) at org.keycloak.services.resources.KeycloakApplication.migrateModel(KeycloakApplication.java:272) at org.keycloak.services.resources.KeycloakApplication.migrateAndBootstrap(KeycloakApplication.java:213) at org.keycloak.services.resources.KeycloakApplication$1.run(KeycloakApplication.java:180) at org.keycloak.models.utils.KeycloakModelUtils.runJobInTransaction(KeycloakModelUtils.java:227) at org.keycloak.services.resources.KeycloakApplication.startup(KeycloakApplication.java:171)” Can anyone have help here on this issue ---

Did you delete any auto-created clients in any realm? The exception yields to migrating the Account client, but if you deleted it, the script will fail. This is fixed in KC 9.x and up (I encountered the same error and did the PR fix). So, try to use KC 9.x or 10.x, this exception should no occur. Alternatively, re-create the Account client. Deleting auto-created clients in a realm is not the way to go. Just disable the ones you don’t want/need, this prevents further issues. ---

Please Share complete logs of the keycloak. There should be another error or warning above the error which you shared with me. Try to share debug logs. Enable logging on keycloak subsystem and change console log handler. $ ./jboss-cli.sh --controller=[192.0.0.0:9990](http://192.0.0.0:9990) --connect [[standalone@192.0.0.0:9990](http://standalone@192.0.0.0:9990) /] /subsystem=logging/logger=org.keycloak/:add(category=org.keycloak,level=TRACE) $ [[standalone@192.0.0.0:9990](http://standalone@192.0.0.0:9990) /]/subsystem=logging/console-handler=CONSOLE:change-log-level(level=TRACE) Thanks & Regards ---

Hi every1, i was able to get this issue resolved. please follow below steps in order to resolve: 1. import realms from import feature in keycloak. you can import all the relams in one go or one file for one realm. 2. create a empty DB and let keycloak point to that db. once keycloak is started this new db is updated with keycloak schema. 3. now in keycloak export json file created in step1 and if success upgrade is done. In case of failure, create realm manually with same name as in old keycloak and then import json or u can import json while creating realm as well.
