The AM Upgrader operates as an inline upgrade mechanism for AM when AM is deployed in LDAP SMS mode. In this mode all configuration for the server is located within the LDAP Configuration Store.
For this upgrade mode there is some automatic upgrade behaviour built into the upgrade framework. This is provided by the ServerUpgrade class. If your upgrade consists of any of the following operations then you may find there is no need to create an upgrade step:
- Service Addition
- Service Removal
- Attribute Addition
- Attribute Removal
- TODO - there may be more.
