WAAS Central Manager Replacement

I have need to replace a WAAS Central Manager (4.4.x). The replacement would have a new IP address. The planned path of migrating is first to setup the replacement as standby and once sync'ed promote to primary. I will then manually update the WAE devices with new IP address.

OLD CM:

WAE# configure

WAE(config)# central-manager role primary

WAE(config)# cms enable

On the standby device, execute the following CLI commands:

WAE# configure

WAE(config)# central-manager role standby

WAE(config)# central-manager address new IP

WAE(config)# cms enable


Is this idea the best approach?

Any idea if the SSL certificates would have to be revoked and re-issued (whether self signed or otherwise)?

Hi,

The steps to replace a CM hardware have been documented under the following bug:

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtz47138

Basically, the steps are the following:

If the CM will be using the same hardware and IP you can restore the CMS database.


If the CM will be using a new name or IP, use the workaround provided by CSCsi59886:


1- Add new CM as standby

2- Make it primary

3- deactivate former CM in new CM GUI

4- delete former CM from new CM GUI (and make sure it s gone from the DB)

5- 'cms deregister' on former CM CLI

7- rename former CM, change its mode and reload.

8- rename the new primary and change its IP address

9- Change the IP and mode of former CM and register it

Regards,

Nicolas
