7.1 Replacing a management server
Replacement of a management server means to use a computer on which JP1/IT Desktop Management 2 - Manager is not installed as the new management server.
The following provides notes on replacing a management server:
- Important
-
The version information of JP1/IT Desktop Management 2 - Manager that will be installed on the new computer and the version information of the product on the old computer must match.
- Important
-
You cannot upgrade JP1/IT Desktop Management 2 - Manager while replacing a management server. Accordingly, install the upgrade before or after replacement.
- Important
-
On a computer running Windows Server 2019, Windows Server 2016 or Windows Server 2012, do not specify the following folders during setup:
-
Folders under system-drive:\program files\WindowsApps
-
Folders in storage areas created by virtual provisioning
-
- Important
-
If the IP address of the new computer is no longer the same as that of the old computer, and you want to change the connection destination of the agent, you need a network configuration in which the new management server and the agent can directly access each other. A network in which direct access is possible means a network in which a host name or an IP address is used for access, and in which the server and the agent can communicate with each other directly via ICMP. In addition, you must be able to pass the TCP protocol port that is used by the management server and the agent.
- Important
-
If you want the management server to inherit the system configuration on the old computer, the IP address of the managed device must match before and after replacement.
For example, if the IP address of the managed computer changes due to a change in the installation location during management server replacement, that computer is not connected to the new management server. If this happens, create an installation set on the new management server to reinstall the agent on the computer. This action connects the computer to the management server.
- Important
-
Manage the database backup on the old computer by using a user ID and password to prevent access by personnel other than the administrator. If an unintended user obtains the backup improperly and then restores it, that user can use the managed devices from the user's management server just as you protect the management server.
- Important
-
If you want to manage devices that were managed on the old management server on the new management server, restore the database you backed up on the old computer on the new computer. If the database is not restored, the agent installed on the managed devices will not be able to connect to the new management server.
If you want to manage new devices on the new management server, you do not need to back up and restore the database. However, if you want to manage the same devices that were managed before replacement, take either of the following actions after replacement:
-
For computers on which an agent is installed: Use the installation set you created on the management server after replacement to reinstall the agent.
-
For agentless devices: Run discovery to include the devices as managed devices.
-
- Important
-
If you connect the old management server to a network without uninstalling JP1/IT Desktop Management 2 - Manager, the agent on the new management server cannot be managed correctly.
This is because both of the servers can connect to the agent, and the agent might enter a state that the administrator did not intend because the management servers have given different instructions. In addition, information reported from the agent by connecting to the old management server is not reported to the new management server. As a result, there might be differences in the information managed by the two servers.
