I have 3 WCS servers, 1 WCS is monitoring 24 WLC's another WLC is monitoring another 26 WLC's and the 3rd WCS is being used for HAL. I know I need to upgrade to NCS first but after that upgrade how can I merge the 2 databases into Prime?
Migrating WCS User Data to NCS 1.1 (for Multiple WCS Servers)
When you migrate multiple WCS servers to the NCS, follow these steps:
Step 1 Stop the WCS server.
Step 2 Export data from the WCS server which is running the most critical data. To do this, follow the steps in the "Exporting WCS Data" section.
Step 3 Export the user data from remaining WCS servers using the following command (for Windows):
export.bat userdata zipfile
Exports only user-created data in the database, saved reports (if -noreports is not specified), map images, license files, mobility services engine backups, location server backups, accuracy test files, controller auto provisioning files.
Note Export userdata is supported only by WCS Release 22.214.171.124 and later.
Full pathname of the compressed .zip file to create.
Note You need to transfer the exported userdata .zip file from the WCS server to the NCS server.
Note For the remaining WCS servers, except the managed devices and maps, no other userdata (such as config templates, reports, users, virtual-domains, and so on) will not be imported. Also, all network-related data (such as events, alarms, statistics, clients, switches, and so on) will not be imported.
Exporting user data related db tables under group: PARTITION_GROUP
Exporting map data.
Completed export of user data related db tables.
Exporting reports, map images, accuracy test files,
controller auto provisioning files.
Exporting Mobility Service Engine, Location Server backups.
Creating compressed export file.
Shutting down database server ...
Database server successfully shutdown.
Data export completed successfully.
Step 4 Do the following:
a. To import all the device data from the managed controllers into the NCS (as root user in ROOT-DOMAIN), choose Configure > Controllers > Add Controllers, choose Zip File from the Add Format Type drop-down list, enter the .zip filename, and then click Add.
b. To import all the device data from the managed autonomous APs into the NCS, choose Configure > Access Points > Add Autonomous Access Points, choose Zip File from the Add Format Type drop-down list, enter the .zip filename, and then click Add.
After you add devices, the NCS pulls all inventory/configuration data from the respective devices.
After you add devices, you can export map data from the WCS (choose Monitor > Maps > Export Map) and import it into the NCS (Monitor > Maps > Import Map).
