Restoring an integration node that is configured on Microsoft Cluster Services (MSCS)

You must complete a specific set of steps to restore an integration node in an MSCS cluster to its original version.

Before you begin

Use the following procedure to restore an integration node that is configured on MSCS to its original version:

In MSCS take the integration node resource offline, keeping the cluster disk and WebSphere® MQ resource online on your primary node.
In an IBM Integration Bus Version 10.0 command console run the following command:
```
mqsimigratecomponents integrationNodeName -s 10.0 -t original_version
```
where integrationNodeName is the name of the integration node and original_version is the number of the version you migrated from; for example 8.0.
In a command console for the version you migrated from, run the following commands:
```
mqsistart integrationNodeName
```
```
mqsistop integrationNodeName
```
This step is required to update the Windows service to point at the binary files for the original version.
With the integration node resource offline, move the integration node cluster group to the secondary node.
In an IBM Integration Bus Version 10.0 command console run the following command:
```
mqsimigratecomponents integrationNodeName -s 10.0 -t original_version -1
```
In a command console for the version you migrated from, run the following commands:
```
mqsistart integrationNodeName
```
```
mqsistop integrationNodeName
```
Bring the cluster disk and WebSphere MQ resource offline.
Start the integration node cluster group on its primary node.
