# Summary of changes

This section provides information on migrating from agmon to NMS OAM. The following list summarizes the changes introduced with NMS OAM:

- The AG board configuration and monitoring utility, agmon, is deprecated. NMS OAM performs board management operations across AG, QX, CX, and CG boards. Utilities included with NMS OAM duplicate and enhance operations formerly performed by agmon.

- The AGM library is deprecated. NMS OAM has an API for initializing and monitoring boards and for performing many other tasks.

- The AG configuration file has been replaced by files with very different structure and syntax. Keywords used in these files are different from AG configuration file keywords.
  The ag2oam utility, included with NMS OAM, translates AG configuration files into the new syntax.

- Previously, the only method of identifying a board in software was the board number. A new identifier, the name, can be used to identify each board, as well as certain software modules and other components.

- The HSI service is deprecated. Hot Swap functionality is implemented as an extended component of NMS OAM. The Hot Swap manager has not changed.

- The QX board configuration and monitoring utility, qxload, is deprecated. NMS OAM performs board management operations for QX boards. For information about migrating QX applications to NMS OAM, refer to the QX 2000 Installation and Developer's Manual.

- NMS SNMP services use NMS OAM. Therefore, SNMP provides information only on boards started using the OAM service.

- Tracing messages are retrieved using the NMS OAM oammon monitoring utility.
