# Migrating OpManager from one server to another

Here are the steps to go about migrating OpManager to a new server:

1. Please click on **Support->About** clicking on the Image icon at the top right of OpManager web client to make a note of the build number of the existing OpManager installation.

2. Take a backup of your existing database by following the instructions on the below link:  
   [https://www.manageengine.com/network-monitoring/help/data-backup-and-restoration.html](https://www.manageengine.com/network-monitoring/help/data-backup-and-restoration.html)

3. For Windows servers, kindly follow the steps mentioned in [this page](https://manageengine.com/network-monitoring/help/server-migration-with-agents.html) before migrating OpManager from one server to another, in case [OpManager agents](https://www.manageengine.com/network-monitoring/agent-based-monitoring.html) are present in your environment.

4. On the new server, download the same build of OpManager from the link below and install it:  
   [http://archives.manageengine.com/opmanager/](http://archives.manageengine.com/opmanager/)

5. Install OpManager first and see if it starts fine. Once it is started, please stop the OpManager service and proceed with the restoration process as stated below:  
   Copy the backup files to the new server.  
   Open a command prompt (as an administrator) and navigate to **\OpManager\bin\backup** directory.  
   You can then restore the backup file using the RestoreDB.bat followed by the path of the backup file on the new server.  

   For example:  
   `...\OpManager\bin\backup>RestoreDB.bat "D:\backup\BackUp_APR25_2010_01_17_21_8051.zip"`  

   Once the restoration is complete, start OpManager service.

6. Copy the files **AdventNetLicense.xml**, **petinfo.dat** and **product.dat** from the OpManager/**Lib** folder (For Version 12 and above) folder of your old server and paste under the same location on the new server. Restart the OpManager service and this will have your license updated.

## Migrating OpManager from Linux installation to Windows installation

Migrating OpManager from Linux installation to Windows installation

1. On the Linux installation of OpManager, click About and check what is the build number of OpManager. Download the Windows setup of the same build from the link below and install it on a test machine.  
   [http://archives.manageengine.com/opmanager/](http://archives.manageengine.com/opmanager/)

2. On the older server installation, take a backup by running the BackupDB.sh file under **\OpManager\bin\backup** folder. Once the backup is complete, a file named **BackUp_FEB28_2005_15_51.zip** (with the current date and time) will be created under **\OpManager\backup** folder.

3. On the Windows installation, create a folder called **backup under \OpManager folder** and paste the backup file from the Linux installation.

4. Now run the RestoreDB.bat file under **\OpManager\bin\backup** folder on the Windows installation with the arguments as below:

   `RestoreDB.bat "C:\Program files\ManageEngine\OpManager\backup\BackUp_AUG10_2012_02_39_44_9101.zip"`  

   Provide the full path of the file.

5. Once the restoration is complete, start OpManager.

3. On the Linux installation, create a folder called **backup under /OpManager folder** and paste the backup file from the Windows installation.

4. Now run the RestoreDB.sh file under **/OpManager/bin/backup** folder on the Linux installation with the arguments as below:

   `RestoreDB.sh "/opt/ManageEngine/ManageEngine/OpManager/backup/BackUp_AUG10_2012_02_39_44_9101.zip"`  

   Provide the full path of the file.

## Limitations of migrating to Linux from Windows:

1. WMI based monitoring functionalities like event log monitoring, windows services monitoring, file monitoring, folder monitoring etc. are not available on Linux.
2. Monitoring of MSSQL/Exchange is not available on Linux.
3. Hyper-V monitoring does not work on the Linux server.
4. Active Directory performance counter will not work.
5. [Server monitoring via agents](https://www.manageengine.com/network-monitoring/agent-based-monitoring.html) is not available for Linux devices.
