How do I migrate product configuration data to vCloud Usage Meter 4.3

You can migrate the product configuration data from your source vCloud Usage Meter 3.6.x appliance to your vCloud Usage Meter 4.3 appliance.

You can migrate the product confirguration data only for products that are supported by vCloud Usage Meter 4.3.

Prerequisites

Back up or take a snapshot of the source vCloud Usage Meter appliance.
You must have the TCP host name or IP address and the usgmtr user password of the source vCloud Usage Meter appliance.
Deploy vCloud Usage Meter 4.3 as a new appliance.

Procedure

Log in to the source vCloud Usage Meter console as root.
Start the SSHD service in the source vCloud Usage Meter appliance by running the following command.
```
service sshd start
```
Log in to the target vCloud Usage Meter console as usagemeter.
Start the SSHD service in the target vCloud Usage Meter appliance by running the following command.
```
su root service sshd start
```
To migrate the source product configuration data to the target vCloud Usage Meter 4.3 appliance, run the command.
```
migrateum hostname
```
Here, hostname is the TCP host name or IP address of the source vCloud Usage Meter appliance from which you are migrating the vCenter Server configuration data.

The migrateum command uses SSH and Secure copy protocol to export the database and keystore files from the source system and copy it to vCloud Usage Meter 4.3.
1. Confirm that you want to migrate vCloud Usage Meter data.
  You must enter the usgmtr password of the source vCloud Usage Meter appliance and confirm that you want to proceed with the data migration.
In the source vCloud Usage Meter console, stop the sshd service by running the following command.
```
service sshd stop
```
In the target vCloud Usage Meter console, stop the sshd service by running the following command.
```
service sshd stop
```

Results

The login credentials for the vCloud Usage Meter 4.3 Web interface are the usagemeter ones, that you set during the deployment of vCloud Usage Meter 4.3.

Important:

You can run the migrateum command only once.

To ensure that vCloud Usage Meter 4.3 is working correctly, run the new appliance in parallel with the source appliance for at least one full reporting cycle.

What to do next

The vRealize Operations Manager product configuration data is not migrated from the source vCloud Usage Meter appliance to the target vCloud Usage Meter 4.3 appliance. If a vRealize Operations Manager server is associated with a vCenter Server instance that you added for metering in the source vCloud Usage Meter appliance, after you migrate the product confirguration data, vCloud Usage Meter 4.3 automatically detects the vRealize Operations Manager server.

To start metering the product consumption data of the migrated vRealize Automation instance, in the vCloud Usage Meter Web interface, you must manually update the vRealize Automation instance details and accept the server certificate.

If you want to retrieve additional certificates and validate the product connectivity, in the main menu bar of the vCloud Usage Meter Web interface, click Products and click Edit and Save for each product.

If you have vCenter Server instances that use an external Platform Service Controller, enter the additional Platform Service Controller information in vCloud Usage Meter. For more information about configuring Platform Service Controller, see How do I add a vCenter Server instance for metering.
