[keycloak-user] Upgrading from Red Hat SSO 7.0 to Keycloak 3.1

[Marcelo Nardelli]

Hi,

At work, we have an installation of Red Hat SSO 7.0 and we were going to
upgrade it to version 7.1. However, I was told that the our Red Hat
subscription won't be renewed, so now we want to upgrade to the last
Keycloak version. Is this (upgrade from SSO 7.0 to Keycloak 3.1) supported?
I've been trying to follow the instructions on the documentation (
https://keycloak.gitbooks.io/documentation/server_admin/topics/MigrationFromOlderVersions.html),
but it's not working. Specifically, when I try to run the migration script
(after copying the old standalone.xml and the keycloak-server.json file)

    jboss-cli.sh --file=migrate-standalone.cli

I get this error:

    Cannot start embedded server: WFLYEMB0021: Cannot start embedded
process: Operation failed: WFLYSRV0056: Server boot has failed in an
unrecoverable manner; exiting. See previous messages for details.


I suppose the Keycloak version used in SSO 7.0 is too old and I will have
to do some manual work here, but I wanted to know if there is some specific
advice for this case...

Thanks,

Marcelo Nardelli
