To upgrade Governance Services you need to make sure you’re running the correct version of Alfresco Content Services.
Check the Supported Platforms and the Alfresco Content Services upgrade paths in the Alfresco Content Services documentation.
When your Alfresco Content Services installation is upgraded, you can apply the new AMP files for Governance Services.
Your existing Records Management data is migrated to Alfresco Content Services.
When you upgrade from a previous version of Records Management to the Alfresco Records Management install, any existing Records Management data is preserved (it is 'patched' in the same way as updated data in the server). The File Plan structures will appear as they did in 1.0 and the previous Records Management site is migrated. Therefore, you do not need to create the Records Management site again.
From Records Management 2.0 onwards you cannot create a record series; instead you create a record category with no retention schedule. The record series is retained as a deprecated model construct to be used when migrating existing record series from a 1.0 installation. This means that any previously created record series will appear and behave as record categories in 2.2, but will be of the deprecated type record series (directly extended from record category). If any custom data was defined for record series in 1.0, this will still appear in the Records Management site, but only for the migrated record series.
Note also that any pre-configured saved searches from your previous version are not available after an upgrade.
