CAS registry migration

[Jeffrey Ramsay]

Hello -

What is the process for migrating the service registry from CAS 6.2 to 6.4? I have used the service endpoints to export the 6.2 registry and then tried to import into the new 6.4 system registry and that fails. Placing the exported json files in the services area fails as shown below -- and this is not the only error; removing the failed section leads to another very similar message.

2021-12-14 07:38:12,198 ERROR [org.apereo.cas.util.serialization.AbstractJacksonBackedStringSerializer] - <Cannot read/parse [{"@class":"org.apereo.cas.services.OidcRegisteredService","serviceId":"https://b....edu:6129/bprep/apex...] to deserialize into type [interface org.apereo.cas.services.RegisteredService]. This may be caused in the absence of a configuration/support module that knows how to interpret the fragment, specially if the fragment describes a CAS registered service definition. Internal parsing error is [Cannot deserialize value of type `org.apereo.cas.configuration.model.core.authentication.PrincipalAttributesCoreProperties$MergingStrategyTypes` from String "replace": not one of the values accepted for Enum class: [NONE, ADD, MULTIVALUED, REPLACE]

You can point the 6.4 system to the 6.2 database; however, the registry data are in two different tables, so what are we supposed to do?

The 6.2 system uses the MySQL table regex_registered_service and 6.4 uses registered_services. I have hundreds of services to manually re add unless I want to strp all but the first six lines from every json file and then modify each using the management service.

That message might mean that you're missing the OIDC dependency in your build.gradle

Make sure you have something like

    implementation "org.apereo.cas:cas-server-support-oidc:${project.'cas.version'}"

Yep, that's included. I only showed the oidc entry but this is occurring for all json objects exported from 6.2.

Thanks,

Ok, I just read the error message more carefully...

Cannot deserialize value of type `org.apereo.cas.configuration.model.core.authentication.PrincipalAttributesCoreProperties$MergingStrategyTypes` from String "replace": not one of the values accepted for Enum class: [NONE, ADD, MULTIVALUED, REPLACE]

With 6.4, CAS seems to have become more picky about requiring the "MergingStrategy" values to be in uppercase. We ran into the same problem; solution was to change  "mergingPolicy": "replace" to "mergingPolicy": "REPLACE" everywhere.

David,

Thanks for your suggestion, I will give it a try.

Thanks again,

-Jeff
