11.3.1.4. Using OpenScape 4000 Assistant Backup & Restore for more extensive
Changes in the System 
If you need to make extensive changes to the system, or if you are
importing a new system version, the following requirements could arise:
- Larger configuration changes should be distributed to all CC-APs as
quickly as possible
- After completing the changes, you should initiate an “unscheduled“ backup. However, make sure that you verify that there is sufficient transmission bandwidth available in the network at this time to complete the backup and the subsequent restore operations of the CC-APs. Remember that you cannot cancel backup and restore procedures that are active. It may be useful to deactivate the backup process before making the changes. -> See the second point. In the OpenScape 4000 Assistant Backup & Restore, go to the schedule for the backup type “AP Emergency“ and click Start now. It is not advisable to use “Backup“ for this. If you do, you must remember to run an EXEC-UPDAT beforehand.
- You should verify new SW (regardless of whether it is a pre-revision bug
fix of an LW or a new system version) on the host system first, before
distributing it to all CC-APs.
- Before importing new SW: In the OpenScape 4000 Assistant Backup & Restore, go to the schedule for the backup type “AP Emergency“ and change the status from “activated“ to “deactivated“. If there are several entries in the schedule for the backup type “AP Emergency“, you must deactivate all entries that could apply during the planned interval.
- After successful verification of the SW: In the OpenScape 4000 Assistant Backup & Restore, go to the schedule for the backup type “AP Emergency“ and change the status from “deactivated“ back to “activated“. If there are several entries in the schedule for the backup type “AP Emergency“, you must activate all entries that you previously deactivated. If the network allows it, it may be useful to initiate an unscheduled backup. -> See the first point.
