Migration of Multiple Mgmnt servers to single + HA Mgmnt server

[gladiatorkev]

Hi,

I currently have an environment where there are two Mgmnt servers (both R55) managing 2 clusters of Nokia IP boxes each and all running CP R55 as well.

I am planning to migrate to a better solution where i will have a single mgmnt server managing all 4 Nokia clusters and then mgmnt HA module.

I plan do do it in the following way:

1: Do a upgrade_export from both the mgnt servers 1 and 2.
2: Get the .tgz files as output from these servers and install them on individual machines
3: On one of the machine do a cp_merge using the objects as well as policies frm the second mgmnt server. This will enable me to have a single mgmnt server with all configs / objects / policies ..etc from both the mgmnt servers
4: Reset SICs at all the Nokia enforcement modules as well there objects on the single mgmnt server and re-establish the SIC for all of them.
5: Create the HA for the single mgmnt server i have just created

Does anybody see any potential issues in the above plan of action.

Appreciate your Inputs.

I Think this is the correct way. We did this last year for 7 management station and with 80 firewalls. We migrated to 4 cma on a provider 1 management server.

But you have to make sure that you don’t have conflicting objects. So make sure you don’t have any object/groups/networks/service with the same name but with diffirent ip or ports.
You also have to export the users separately and you cannot export user groups, you have to ad the groups manually and then import the users.

I would recommend testing this al first in a lab environment.

Yea.. thats correct...

If you have similar objects in your diff smartrcenters, i would suggest to clean up all those objects -or- make them excatly the same.. char for char..

cp_merge will copy object from the "export" to the local machine you're doing it on... same objects (name, char for char) will not be imported, once that is done, you can import the policy.. if there are missing objects, the import policy will fail...

From my painful experience, do note one thing... make sure you know your objects close to inside out.... one thing is that since same name objects are not imported.. i give you one simple scenario to ponder:

on SCS1:
test_group
host1
host2

on SCS2
test_group
host1
host2
host3

Now you have these 2 "conflicting" objects... can you "control" which is imported in or should stay the same???

Hi,

First of all thanks for the very useful inputs.

I had a question though..
What if i need to change the "IP address" as well as the "Host name" of the new management server that i am setting up in place of the two earlier management servers..?!

In such a scenario, what all changes would i have to do after the Upgrade_export / Import..?

Thanks in advance.

Run cp_merge to do whatever u need to combine the 2 scs..
upgrade_import into new machine using SAME IP
Login to both Smartupdate and smartdashboard
Unattach all licenses for the scs
Change Hostname/IP
Change actual ip on machine

I would suggest to run this on a seperate machine entirely... try everything out... make sure it all works, but doing on your actual production machine..
