Catastrophic error after database migration

[Mike Bretz]

I installed a new instance of Confluence 3.5.13 on a new box and pointed it to a new Postgres database. Everything worked perfectly.

I stopped the new instance and migrated all of my data from another Confluence instance. All tables copied perfectly.

When I brought the new Confluence version up, all I got was a white page with this error:

Error occurred during template rendering: Invocation of method 'getLogoForGlobalcontext' in class $Proxy45 threw exception org.springframework.orm.hibernate.HibernateObjectRetrievalFailureException: No row with the given identifier exists: 0, of class: com.atlassian.confluence.core.ContentEntityObject; nested exception is net.sf.hibernate.UnresolvableObjectException: No row with the given identifier exists: 0, of class: com.atlassian.confluence.core.ContentEntityObject at template/includes/macros.vm line 1651, column 43 . Contact your administrator for assistance.

I assume this is related to the migration, but everything migrated perfectly with no errors so I am unsure what I did to cause this error.

Error was related to data types and values, was not copying null values properly or converting CLOB/BLOB into the correct Postgres types.

Did you follow the guidance given here: https://confluence.atlassian.com/display/DOC/Migrating+Confluence+Between+Servers There's a lot more to this task than just copying tables, as the guide explains. How are you storing the attachments that originate from your original instance, and have these moved to a new server?

Were you trying to migrate a Confluence 3.5.13 content to another Confluence 3.5.13 on another server or were you trying to migrate Confluence 3.5.13 database to another database type?

If you are migrating Confluence between servers, you can refer here for details: https://confluence.atlassian.com/display/DOC/Migrating+Confluence+Between+Servers

If you are migrating Confluence database to another database , you may refer here: https://confluence.atlassian.com/display/DOC/Migrate+to+Another+Database

If you are simply moving your DB from one server to another you can just change the JDBC URL in <confluence.home>/confluence.cfg.xml (if you are using a direct JDBC connection) or in the definition of your datasource (if you are connecting via a datasource).
